Maths accessibility for colour blindness
Design resources that do not rely on colour alone.
Quick answer
Maths accessibility for colour blindness means designing maths resources that help children who are colour blind to understand and enjoy learning maths without relying only on colour. This includes using patterns, shapes, textures, numbers, and words to support learning.Learning outcome
By the end of this page, you will understand how to make maths learning inclusive for children who are colour blind, so they can join in and enjoy all maths activities just like everyone else. Success signs:- You can explain why some maths materials need to use more than just colour
- You can identify different ways to show maths ideas without colour
- You can suggest ways to make your own maths games or activities more inclusive
- You can spot when maths resources might be hard for a colour blind child to use
Why this matters
Maths is full of patterns, shapes, numbers, and ideas that don't need colour to be understood. When we design maths activities that don't rely only on colour, we help all children learn and have fun. This is especially important for children who are colour blind because they might miss important information if only colour is used. Making maths accessible helps every child feel included and confident in their learning.How it works
Making maths accessible for colour blindness means thinking about how to show information in more than one way. Instead of just using red and blue to show different groups, we can use:- Different shapes or symbols
- Patterns or textures
- Numbers and words
- Physical actions or movements
- Written labels or descriptions
Examples you can see
Let's imagine you are learning about counting groups of toys. Instead of using red and blue toy cars to show different groups, you can:- Use different shapes: red circles for one group, blue squares for another
- Use different textures: one group has smooth toys, another has bumpy toys
- Use numbers: one group has 3 toys, another has 5 toys
- Use words: one group is "toy cars", another is "toy trucks"
Try it as a mini adventure
Adventure: The Colour Blind Explorer You are a brave explorer who has discovered a magical maths land where everything is made of shapes and patterns instead of colours. Your mission is to help the local children learn maths by making their activities more inclusive. First stop: The Shape Garden You see a garden with 4 red flowers and 3 blue flowers. Instead of just using red and blue, you must find a way to show these groups using different shapes. What shapes could you use? Second stop: The Pattern Playground There are 5 blocks in a row, and you need to make a pattern. What pattern could you make that doesn't rely on colour? Try using shapes, sizes, or positions. Third stop: The Number House You are helping a friend count their toys. Instead of using red and blue toys, you use a mix of different types of toys. What could you do to make sure your friend can follow along?Common mistakes
- Mistake: Using only red and blue to show different groups in a maths activity Why it happens: Adults might not think about how colour blind children see the same materials Fix: Add shapes, numbers, or labels to show different groups
- Mistake: Assuming all children see the same information in a chart or diagram Why it happens: Adults might not know that some children have trouble distinguishing certain colours Fix: Use clear labels, symbols, or patterns to show information
- Mistake: Not thinking about how to make maths games more inclusive Why it happens: People might not know what to change to make games more accessible Fix: Add different ways to show information, like using shapes or numbers
Parent and carer guide
Parents and carers can help by:- Looking at maths materials with a colour blind child and seeing if they can understand the information
- Adding extra details like shapes, numbers, or words to help show information
- Using different types of materials, like blocks or drawings, to show the same idea
- Encouraging the child to explain how they see the information
- Playing maths games together and making sure the games are easy for everyone to play
Practice questions
- How could you show 5 red circles and 3 blue triangles in a maths activity without using only colour?
- What could you add to a chart that shows 4 green stars and 6 yellow stars to make it easier for a colour blind child to understand?
- What are 3 different ways to show 2 groups of toys without using only red and blue?
- Why is it important to make maths activities accessible for children who are colour blind?
- Can you think of a maths game you play at home that could be made more inclusive? How would you change it?
- You could use different shapes (circles and triangles), different textures (smooth and bumpy), or numbers (5 and 3) to show the groups
- Add labels like "green stars" and "yellow stars", or use different shapes like stars and moons
- Different shapes, different textures, or numbers to show the groups
- It helps all children learn and feel included in the classroom or at home
- Answers will vary, but could include using shapes, numbers, or words instead of only colour
