About Dex
Dex notices what others miss — patterns, numbers, relationships and the tiny details. He understands the world through logic and maths, and he’s brilliant, thoughtful and honest about it.
For Dex, the real challenge isn’t solving problems — it’s understanding people! He leads the Numeracy Root, where counting, patterns and problem-solving turn into puzzles worth cracking.
Patterns are everywhere — if you look closely.

How Dex helps your child grow
Counting, patterns, logic and problem-solving — how children make sense of number and the world.
Number & counting
Counting 1–5, then 1–10, teens and 20, on to 100 and skip counting — building all the way to place value.
Number sense
Subitising (seeing how many at a glance), one-to-one matching, ten-frames, and comparing amounts.
Patterns & reasoning
Copying and extending patterns — AB, then ABB/ABC, growing patterns and number patterns.
Shape, space & measurement
2D and 3D shapes, position and direction, and comparing size, length and time.
Operations & problem-solving
Part-part-whole thinking, addition and subtraction within 10 then 20, and simple two-step problems.
