Easter is just around the corner and I’ve been busy creating more themed computing activities so that your pupils can demonstrate their computational thinking and coding skills.
Click to get the plan and resources
I’ve prepared step-by-step lesson plans and some teacher/pupil computing resources that I’m using and have added to iCompute to celebrate Easter and/or Spring.
It’s Easter and the Easter Bunny has forgotten where she has hidden all of her eggs. Challenge your pupils to create algorithms and program the bunny to get all of her eggs in her basket any way they know.
Pupil Support Card
As usual, lots of opportunities for differentiation. For instance, less able pupils could use pupil support cards (see Egg Hunt card which is included in the pack) and/or write a more simple collecting less eggs. Your more able pupils could:
program the ice-cream truck sprite to move across the x-axis
program the hot-air balloon to fly
add the Easter eggs to a list variable when collected
add ‘enemies’ to thwart the Easter Bunny in her quest
add extra, increasingly difficult, levels (e.g. mazes to navigate)
Ideas for differentiation, extension and enrichment are included in the lesson plan. Lots of opportunities to be inspired and get creative.
I’ve also created an Easter Egg Hiding Robotics activity using Sphero SPRK+ and Sphero Edu. The Easter Bunny (Sphero) needs your help programming it to hide a collection of Easter Eggs (hollow plastic balls or eggs filled with treats). Lots of cross curricular links here with Science and Mathematics so get rolling.
The file includes all Category blocks along with Extensions: Microbit, Makey Makey, Video Sensing, Pen, LEGO WeDo, LEGO EV3, Music, Text to Speech and Translate.
Available to download by clicking/tapping the Periodic Table of Scratch 3 Blocks image (see below). The blocks can be edited and scaled using image editing tools (e.g. Illustrator, Inkscape, Vectr). The blocks are also provided in .png format.
It’s important that children be given opportunities to interact with physical programming blocks to help them understand both their function and the underlying concepts. I use them in groups for the children to program me and/or each other as well as programming using Scratch 3 itself.

Also available in the same format are Scratch 2.0 blocks and Scratch Jr blocks from this post.
Regular readers of this blog will know that I teach primary computing and have recently added a Primary Robotics scheme of work to iCompute. Part of this scheme involves working with Sphero and programming the robotic balls using Sphero Edu. To help avoid repetitive strain injury by double tapping each block to find out what each command does, I’ve produced this handy Sphero Commands Helpsheet. Now updated to include the new look Scratch blocks.

This post follows on from a previous post detailing my experiences of teaching primary computing, coding with Sphero 2.0. Following the successful loan of Sphero 2.0 from Lancaster University as part of my role as a Computing at Schools Primary Computer Science Master Teacher, my school bought a class set of Sphero SPRK+ to support teaching primary computing and use elsewhere across the curriculum.
Sphero SPRK+ is certainly more stable than Sphero 2.0. Because they are equipped with Bluetooth SMART technology they are much easier to connect to devices and, thankfully, don’t require any of pairing and labelling that I needed to do with Sphero 2.0 for classroom management. Here, connections are made between your device and the robot simply by tapping them together. That said, do check your devices are compatible with SPRK+ as they need Bluetooth 4.0 LE to work. I found out only seven of our iPads at school work with my new set. Luckily, we only have six Sphero but it could have been a very costly mistake!
Sphero SPRK+ has lights, sound and voice. I made links to the work we had been doing in cryptography (iCompute, Year 5, iCrypto) studying Morse Code by using Sphero’s strobe blocks to flash lights representing the dits and dahs of letters in secret messages (changing colours between letters to make decoding easier). For the solutions, the children then added speak blocks after each sequence of Morse code, which said verbally what the letters were.
Another great feature of the Sphero Edu app is being able to easily see (and export to other apps) Sphero’s live sensory data. This is brilliant for cross curricular work, particularly maths and science. Sphero is packed with sensors — gyroscope, accelerometer, location, etc… Pupils can see the real time value of sensors within Sphero Edu with visual graphs. If you throw Sphero like a ball, pupils will see the accelerometer data rise and fall. Similarly, when they construct a maze, they can use the data to track location, distance, and speed.

Last, but not least, Sphero Edu with Sphero SPRK+ includes a Program Cam feature which allows pupils to take a videos or images of programs while they’re running. Pupils can narrate what they’re created, demonstrate their learning (and ultimately mastery) and share their work with a wider audience.
Pupils naturally love working with Sphero, they think they’re playing. Under the guise of play, they’re actually learning invaluable programming skills alongside learning about everything from physics to art! That’s learning at its best. The SPRK+ edition, combined with the Sphero Edu app, brings so much more to the table to support teaching and learning – particularly in STEM subjects. They’re expensive but with the right blend planning and imaginative resources, using Sphero SPRK+ in your school can extend to all areas of the curriculum.
Ready to roll? The possibilities are exciting!
Our school purchased six Sphero SPRK+ at full price. I have produced lesson plans and resources for iCompute that use Sphero 2.0 and Sphero SPRK+ but am in no way affiliated with Sphero Inc.
Visit iCompute to find out more about primary robotics
I’ve been teaching primary robotics for some time now as part of the computing curriculum that I write for iCompute. I teach with and have produced schemes of work for robotics from EYFS to Year 6 using BeeBots, LEGO WeDo, Sphero and parrot drones to name a few.
Whilst teaching computing itself can be daunting for many teachers, the prospect of the added pressure of actual things being whizzed around classrooms through code can push many to avoid the controlling physical systems aspects of the National Curriculum for Computing altogether!
The rapid pace of advances in technology means children are growing up in an age dominated by embedded computer systems and robotics. It is crucial they have an understanding of its impact on the world and their own futures. Teachers need to be in a position to provide pupils with the level of knowledge, understanding and skills they need to live in the modern world.
Including Science, Technology, Engineering, and Math (STEM subjects) in early education provides a strong motivation for learning and an improvement in progression. Teaching robotics is a great way of connecting with children and enables schools to engage the potential engineers and computer scientists of the future.
Most curricula in primary schools cover science and mathematics, but we need to do more in teaching problem solving, computer science, design, technology and robotics.
The use of robotic systems and robotics as a subject offers an introduction to the engineering design process and sets children’s learning in a fun, meaningful, contexts. The fundamental principles of computer science are applied and made easier as models and devices can be designed, constructed, programmed and executed in front of pupil’s eyes. This makes it much easier to learn what robots can and cannot do: their capabilities and, crucially, their limitations.
We’ve recently put all of our robotics units into one primary robotics pack that covers the controlling physical systems aspects of the National Curriculum for Computing at Key Stage 1 and Key Stage 2 (pupils aged 5-11).
I’m also including some free activities as part of our contribution to this year’s Hour of Code, adding to those already featured last year and still live. As the Hour of Code launches each year in December, I’ll be adding a nice festive twist to my teacher-led activities. Hint: Santa’s sleigh is broken but he has a drone! Here’s a sneak peek of the cover…
HOC iFly Cover
Check out my other blog posts for teaching tips and advice about how to manage programming physical devices with younger children. I cover:
Using drones in schools has the potential to take learning, literally, to a higher level. As they continue to become increasingly practical, attainable, tools for education, teachers around the world are now using drones in their classrooms for STEM and STEAM activities.
In computing, programming drones helps develop children’s skills in algorithms, programming and computational thinking as well as addressing the ‘controlling physical systems’ objectives of the National Curriculum for Computing at Key Stage 2. Exciting curricula and drone lesson plans are being developed that help teachers develop confidence and make the most out of connected devices.
Drones are revolutionising business and industry: engineers use the technology for site surveys, filmmakers capture images that would otherwise be unseen, drones are used in agriculture; farming; conservation; military operations and parcel deliveries. The potential for the application of drones and the rapid growth in the technology is huge. Understanding how they work, their potential and how to control them through coding prepares children for the modern working world.
iCompute lead the way in teaching and learning using educational technology. In anticipation of 3D robotics becoming the next big thing in education, we have extended our connected devices offering of comprehensive, step-by-step lesson plans, computing resources and assessment toolkits using Sphero and LEGO™ WeDo by adding an amazing, creative, 6-8 week coding with drones unit aimed at upper KS2 Computing (pupils aged 9-11 or higher).
Children learn how to program parrot drones to fly, create aerial shapes, navigate obstacles, fire ‘missiles’, pick up and drop objects all set in imaginative contexts. They program Santa’s ‘sleigh’ to deliver presents before going on an epic journey to a Galaxy Far, Far Away to take out the Death Star for the Rebel Alliance!

I recently published two new 4-6 week physical programming units to iCompute’s Key Stage 2 scheme of work; which I blogged about in my post Teach Programming with LEGO™ WeDo
I admit to a rising sense of panic as I approached my first session: young children, small LEGO parts, computers and stuff that moves! However, we’ve been having a great time and thought I’d share some of the practises I’ve found necessary to manage these very active learning lessons.
First of all, get organised before each session. I’ve found it’s much better to work on the floor to prevent bouncing bricks, so book out the school hall if you can or clear your classroom of desks. I’ve assigned each pair of pupils a LEGO WeDo Construction kit and a labelled basket for their models. I also arranged space in the classroom for a ‘robot parking lot’. Whenever I need everyone’s attention, or if we’ll be working on the same model a few weeks in a row, we park the robots in their baskets on top of the construction kit boxes. This helps keep the kits organised so that, combined, the model and the kit = a full construction kit.
You need to be really firm about pupil movement around the space you’re using with LEGO parts! I use hula-hoops placed around the hall with big gaps between them. I explain the necessity of keeping the models and construction kits within hoops to that we don’t lose the parts. The children have been great, understanding the clear rules and why we have them.
Organisation is key!
In order to work on the floor, you’ll need either laptops or tablets. If you don’t have either, the children can transport their models in their baskets (always with their kits) to the desktops; but make sure they have plenty of space between them to program and operate the models.
I used the amazing LEGO Digital Designer to put together building instructions as a basis for each of the models the children would be making and programming. Don’t worry, you won’t have to if you are an iCompute school because I’ve done all that for you. Simply print and hand out to the children. If you fancy having a go yourself, you can virtually construct a model of your choosing and then opt to create the build instructions which your can display in a web browser or print. Love it!
Build Instructions for LEGO WeDo
Whilst build instructions can be vital for some pupils, there are still plenty of opportunities for creativity for others and I allow those the freedom to design, create and program their own models with only a rough guide.
I’ve been really impressed with how well the children have responded to physical programming and how smoothly the lessons have gone. I hope some of you find my tips useful and please let me know how your lessons go.
This week sees the launch of iCompute’s new six week programming unit for Year 3 and 4-5 week unit for Year 4 which uses LEGO™ WeDo to teach children how to program robots and models in primary computing lessons.
Lego WeDo is a fantastic opportunity for children to bring the physical world to life through code. They build models using the bricks they know and love and then program them interact with the world around them!
Using robotics promotes interest in science and engineering, as well as computer science and helps develop motor skills through model building. Mechanisms, built by and ultimately designed by, the pupils themselves set computer programming in a meaningful context. Children learn more quickly when a model executes a program, physically, right before them.
The robotics elements of LEGO WeDo include motors and sensors. Our new units do not require the full educational LEGO WeDo sets to be bought. Schools that already have plenty of bricks and parts can simply buy the robotics parts that will enable models to move, sense and interact with the physical world.
LEGO WeDo has two versions 1.0 and 2.0. Our units provide support for both and the principle robotic parts remain the same at their core (albeit with enhanced features for 2.0).
The Hub: The WeDo hub connects models to your device. You can connect up to two sensors (motor, distance sensor, or tilt sensor)
The Motor: When connected to the hub, the motor can be programmed to turn on/off. It can also be programmed to adjust power, direction and duration
The Distance Sensor: The distance sensor can detect how far away an item is in front of it
The Tilt Sensor: The tilt sensor detects how far it’s tilted from left to right.
You can also connect and program LEGO Power Function lights which do not come with WeDo packs as standard but can be bought on their own and connected to the hub too.
As already mentioned, you can buy the robotic parts separately if you have plenty of LEGO bricks; however it is still possible to pick up education sets of WeDo 1.0 at a fraction of the price of WeDo 2.0. Search online for LEGO™ Education WeDo Construction Set 9580 (make sure it’s the construction set you are buying). I managed to buy 6 sets of WeDo 1.0 at £70 each compared to £150 each for LEGO™ Education WeDo 2.0 Core Set 45300.
Programming LEGO™ WeDo
iCompute uses MIT’s Scratch to program models. LEGO WeDo does have it’s own software that comes as part of the kit, but I don’t feel it offers the same opportunities for enhancing physical programming through storytelling so have chosen to use Scratch instead.
There are two versions of Scratch: 1.4 and 2.0. Scratch 1.4 is an offline editor that you download and use without the need for web access. Scratch 2.0 is available as both an online and offline version. Regular readers will know that I prefer 1.4 for primary aged pupils as the interface is cleaner and the debugging options are better. Scratch 2.0 however does allow models to be connected to tablets, as well as computers. You can use both versions of WeDo with Scratch 2.0, however you need to install a device manager and extension in Scratch 2.0 for them to work.
The teacher guides contained within the unit provide comprehensive guidance on the options and their respective setups.
Using Scratch and LEGO WeDo enables pupils to create some amazing models and stories to accompany them.
What Pupils Can Do with LEGO™ WeDo and iCompute
Programming, using software , designing and creating working models
Using the software to acquire information
Using feedback to adjust a programming system output
Working with simple machines, gears, levers, pulleys, transmission of motion
Measuring time and distance, adding, subtracting, multiplying, dividing, estimating, randomness, using variables
Doing narrative and journalistic writing, storytelling, explaining, interviewing, interpreting
Design: Use STEM principles to explore Science, Technology, Engineering & Mathematics and design models
Build: Improve motor function, communicate and collaborate with others in building working models and robots
Program: Create animated stories, and program models to interact with the story & physical world
Digital Literacy: Create factual and imaginative animations and narratives that explain, interpret and tell stories
Test : Use physical output as feedback to to detect errors easily
Debug: Correct errors found when models don’t behave as expected
Evaluate: Critically analyse work and that of others and discuss what is good, or not so good, about them
Improve: Revisit models and code then cycle through this process from ‘Design’ onward to make things better
I’ve created an updated version of a full set of Scratch blocks (Scratch 2.0) which now includes the blocks inside the Sensing, Operator, Data, Custom palettes and LEGO™ WeDo motor blocks. Available to download by clicking/tapping the Periodic Table of Scratch blocks image (see below). The blocks can be edited and scaled using image editing tools (e.g. Illustrator, Inkscape, Vectr). The blocks are also provided in .png format.
It’s important that children be given opportunities to interact with physical programming blocks to help them understand both their function and the underlying concepts. I use them in groups for the children to program me and/or each other as well as programming using Scratch itself.

As I mentioned in a previous post, I have recently written a primary programming robotics scheme of work as part of my role as a primary computing master teacher with Computing At Schools and having been kindly loaned five Sphero. @cas_lancaster will be lending these lesson plans and resources out as part of their equipment loan scheme and the complete unit and associated resources, assessment guidance etc, now forms part of the iCompute for iPad scheme of work.
Today, I presented at #CASLancaster16 conference about my experiences of teaching with Sphero. Check out my posts elsewhere on this blog for tips on teaching with physical systems and visit iCompute Free Stuff to download the free robotics resources I contributed to support The Hour of Code.
Also, check out this post which is an updated version of my teaching experiences with Sphero SPRK+ Edition.

As part of my role with Computing At Schools (CAS) as a Primary Computer Science Master Teacher, I have recently been fortunate enough to teach using Sphero, having been lent a set by @cas_lancaster. The task was to produce a set of step-by-step Sphero lesson plans and associated teacher and pupil support materials for primary teachers to use. That is all now done and I’ve had great fun creating our new robotics unit – iCompute with Sphero – which forms part of our iPad pack , as well as being available separately. It will be lent out to other local schools by @cas_lancaster. Teaching progressive lessons using Spheros enables primary schools to meet a number of the objectives of the National Curriculum for Computing at Key Stage 2 Specifically:
design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; solve problems by decomposing them into smaller parts
use sequence, selection, and repetition in programs; work with variables and various forms of input and output
use logical reasoning to explain how some simple algorithms work and to detect and correct errors in algorithms and programs
select, use and combine a variety of software (including internet services) on a range of digital devices to design and create a range of programs, systems and content that accomplish given goals, including collecting, analysing, evaluating and presenting data and information

iCompute – Features Flowchart
Here, I share my experiences of using Sphero 2.0 with primary pupils and give some general advice and classroom tips about how to use them effectively, engage and challenge your pupils. See this post which details my more recent experiences of teaching using Sphero SPRK+ edition.
What is Sphero?
Sphero is a robot ball with several features that can be controlled though apps and also includes the facility for pupils to create their own computer programs. The main features are:
Rolling – Sphero can roll at specified speeds and directions
Colours – Sphero can light up to a specified colour
Bluetooth – Sphero connects to mobile devices through wireless Bluetooth
As Spheros are connected to iPads via Bluetooth, preparing to use them in your classroom before your roll up brandishing them and creating general hysteria is vital! Make sure all are fully charged and that your have paired each to a particular tablet in advance. Each Sphero flashes a unique sequence of colours when they are ‘woken’ which can be used to identify them. A Sphero will appear on your tablet’s Bluetooth list using the initials of the three colours it flashes in order, Eg. Sphero-RGB for a colour sequence of Red, Green and Blue. Update: Connecting Sphero to tablets is much easier and more reliable since Sphero SPRK+ edition has been released (which I now have and teach with). Here, you simply hold Sphero close to your iPad to make a connection.
For Sphero 2.0, I added stickers to each of the Spheros with their unique name, as ‘YGO’, ‘RGW’ etc., and also to the corresponding tablet I’d paired it to. This made distributing them and the iPads much easier when in class. This isn’t necessary if using SPRK+.
You need lots of space to use these. I used the school hall. I refer back to ‘Preparation’ for this as it may be something you need to organise. I forgot on my first session and arrived with a very excitable class to a hall full of lunch tables. The first half of my lesson therefore involved getting those out of the way.
You can also buy covers called a ‘Nubby’ for outside use.
I tried this with one of my classes and we had to come back inside as it was sunny and therefore impossible to see Sphero’s tail-light: essential to be able to aim it to move in the direction you want it to go. Also, we had iPads and the children couldn’t see the screens. When our school went on to buy the SPRK+ edition of Sphero, we didn’t bother buying the covers.
Now on to the good stuff. My specialism is teaching primary pupils aged 3-11. I think coding with Sphero is suitable for Key Stage 2 pupils, children aged 7-11.
I suggest your first session focus on teaching the children how to wake Sphero, Orient (aim) it and control it using the standard Sphero app. Each Sphero (2.0 version) comes with, amongst other things, a pair of ramps and once the children have got used to moving Sphero forward and backward with reasonable accuracy, add the ramps and other obstacles to make things interesting and develop accuracy further. The SPRK+ edition, doesn’t have ramps but has tapes and measures instead.
A lesson, including step-by-step instructions for both teacher and pupil for this are available in our robotics pack.
iCompute with Sphero
The following lessons progress to using the drive function of the Sphero Edu app enabling the children to gain greater control and begin to understand that Sphero can be controlled to perform specific actions.
I then move things on for the rest of the unit to programming Sphero using Sphero Edu.
We created quizzes that the children programmed Sphero to move and change colour to answer. This presents great cross-curricular opportunities. We create algorithms and program Sphero to be our dance partners for Physical Education. Also, mazes to navigate with excellent links to Mathematics for distance, direction and angle work. The children also program Sphero to travel the globe, linking to Geography, using a free floor map from National Geographic.
Using robotics in the primary classroom presents creative and engaging opportunities for the children to extend what they have learned about algorithms and programming in Computing by understanding that physical systems can be controlled too. With the right blend planning and imaginative resources, using Sphero’s in your classroom has the potential to inspire the next generation of software designers and systems engineers! The possibilities are exciting…
