Math you can touch.
Mathumo is a math app where children learn by doing: moving blocks, filling ten frames and walking number lines, one small step at a time, from counting to 5 up to numbers to 1,000.
Ages 4 to 8 · iPhone and iPad
Objects first. Numbers when they make sense.
Touch, then see, then write
Every idea starts with things to move: counters, blocks, shapes. Pictures come next, and written sums last.
Watch me, your turn
The first time a new kind of activity appears, Mathumo shows how it works. Then your child tries, and that try is never marked.
Hints, not buzzers
A mistake brings a hint: a highlight, a first step, a simpler model. No harsh sounds, no penalties.
A fresh plan each day
Sessions of 5, 10 or 15 minutes mix new learning with review, so skills stick.
