We all know what a struggle it can be to get children to engage with a concept, particularly when we only have a pencil and paper to help us explain it. The more hands-on we can make it, the better. So…
What better way to get children’s engagement than to use sweets?
Here are a few activity ideas that you can complete with a pack of colourful sweeties. For example, Skittles or Smarties would work well. These activities help to bring learning to life, give the learning a purpose and, perhaps most importantly of all, you get to eat the sweets at the end!
To begin, take your sweets and sort them by colour. Using a few packets together helps to create a larger sample size for your data handling. Younger children will enjoy ordering them into a simple pictograph, illustrating which colour is represented the most. Older children can instead represent this information in a bar chart. If you’re looking for a further challenge, move on to creating a pie chart, calculating the fractions and percentages of each colour. You could also compare your sweetie data with a partner, considering the following questions:
What do you notice about your graph?
Was there an even distribution of colours across the packets?
Which two colours have the maximum difference between them?
Shape, Space and Measure
Estimating and Comparing: Before you open the packet, estimate how many sweets you think will be inside it, including how many of each colour. Then open it up and find out if your estimation was correct! It’s interesting to compare packets, exploring whether there is an even distribution of each colour. Older children could calculate the ratios of different colours.
2D Shapes: Younger children could arrange their sweets to create different 2D shapes, as shown in the photo above. They could then count how many sweets fit into each shape. Another activity could be to create symmetrical patterns with the sweeties, or even to create half a symmetrical pattern for a partner to complete. Just be careful your fingers don’t get to warm and melt the coating off the sweets!
Number patterns: This is a really fun way of exploring patterns! Begin a sequence for your child to complete, discussing what the pattern is and how they knew what colours to add next.
This activity is really easy to resource and the results are always amazing to watch! Arrange your sweets in a symmetrical pattern around a plate, pour warm water into the middle and watch the coating on the sweets diffuse, creating a beautiful pattern in the water.

There’s something about origami that really seems to capture children’s imagination. In most of the classes that I have taught over the years, there has been at least one child with a real passion for origami. Many a show-and-tell has been dominated by incredible paper-folding creations, from water bombs to paper dragons. Think back to your own school days; which of these origami classics do you remember creating?
Origami is the ancient art of Japanese paper folding and for many, a love of origami stems from childhood. As much as we might marvel at this paper art-form, do we see its potential beyond an interesting pastime? Origami has evolved to be much more than paper folding. Here are some examples, with real-world applications within areas such as engineering, medicine and technology.
At a primary school level, origami is a fantastic way to explore mathematical concepts including geometry, fractions and angles. Turning a simple square of paper into a piece of completed origami involves a lot of mathematical thinking. Origami instructions involve following steps of folds, often referred to as ‘crease patterns’, in order to create different geometric constructions. Children will need to use knowledge of directionality and angles in order to complete these correctly. Throughout the process they will create other shapes starting from a square including equilateral triangles, pentagons and hexagons. Patterns also feature heavily in origami.
The TED talk above, entitled ‘The math and magic of origami‘ explains in more detail about the complex mathematics involved in origami.
Many of the real-world applications for origami can be found within engineering. Take the example of car airbags. Did you know that their compact, quick inflating design was inspired by origami? Engineers took inspiration from origami patterns and folding methods to deploy how the airbag is stored and deployed. Engineers are continuing to draw upon origami techniques when developing new structures and technologies.
In 2003, a new, origami-inspired heart stent design was created. Designed around an origami water bomb base, the purpose of the stent was to enlarge clogged arteries and veins. The origami design allows the stent to be expanded to different sizes depending on its application. Likewise, origami-inspired forceps are helping to revolutionise robotic surgery, allowing for delicate, precise cuts.
There are plenty of examples of origami-inspired space technology. One such is the solar array. The combination of different folds expands into a large, flat circular surface. These solar arrays can then be used to convert solar energy into electrical power. More examples of how NASA engineers use origami to design future spacecraft can be found here:
And all this is just the start! I hope this blog has inspired you to find out more about the real-world applications of origami. Do let me know your thoughts and further ideas via social media or in the comments section below.
