A visual, colour-coded table that helps children understand number relationships at a glance.
Its simple layout supports alignment, reduces working-memory load, and makes addition and subtraction clearer and more predictable — both at school and at home.

Why COMtable works

Through its colour-coded structure, COMtable makes number patterns immediately visible — and allows children to write down the intermediate steps of a mental calculation instead of holding everything in working memory.
This reduces cognitive load, builds confidence, and helps them practise the core strategies of mental math: composing and decomposing numbers, bridging through 10, and aligning values clearly.

Who is it for?

Created originally for dyslexic students aged 6–10, COMtable is equally helpful for any child who struggles with number alignment, place value, or remembering the intermediate steps of a calculation. By supporting weak working memory, it helps pupils follow the correct order of operations — both in mental maths and in written column calculations — reducing confusion while strengthening core mathematical strategies.

Try it in class or at home

Specifically designed for addition and subtraction, COMtable is simple to introduce in both one-to-one and small-group settings.
You can use it to explore number patterns, guide pupils as they break a calculation into steps, or practise quick “Make 20” and bridging strategies. Its visual layout helps children  stay focused and engaged, while strengthening the reasoning behind each choice they make.

Discover how to use it

With the erasable pen, children can actively trace the start, mid and end points of any calculation.
The laminated surface lets them write, check, correct and try again — keeping track of each step directly on the table.
By marking intermediate values instead of holding them in mind, pupils stay focused on the strategy and find even multi-step additions and subtractions easier to follow.
Thanks to a small colour-guided card, they naturally learn to line up units, tens and hundreds with clarity and consistency.

What’s included in the set

The COMtable set comes in a sturdy, waterproof button-folder, ideal for classroom or home use. Inside, children receive the laminated table, an erasable pen, a short guide with examples, and a small double-sided practice card — with a colour-guided alignment layout on one side, and open graph space on the other for free exercises and quick notes.
