Letters, numbers, tracing, and the rest of what your kid plays
Twelve activities, each one narrated from the first screen. Here's what each one actually does.
Letters and Sounds
Kids see a letter, hear its sound, and pick the matching picture. It starts with the easiest letters and adds new ones once the last few feel comfortable.
Word Builder
Simple words appear one at a time. Kids drag letters into place and hear the word read back when they get it right.
Sight Words
The words that show up everywhere in early reading come back again and again, in short rounds, until they feel familiar.
Numbers and Counting
Counting starts with one object on screen at a time and builds up gradually, always with a number and a picture together.
Math
Addition and subtraction shown with pictures first, numbers second, so the idea makes sense before the symbols do.
Tracing
Letters, numbers, and shapes to trace with a finger or a mouse, with a gentle line to follow and a cheer at the end.
Shapes and Colors
Matching and sorting games built around basic shapes and colors, good for kids who are just starting to name what they see.
Music Maker
An on-screen instrument kids can tap to make their own sounds and short tunes, no lessons required.
Memory Match
The classic flip-two-cards game, using pictures instead of words so younger kids can play too.
Patterns
Kids figure out what comes next in a sequence, then get a turn to build a pattern of their own.
Robot Coder
A gentle first look at coding: kids drag simple instructions together to move a robot around the screen.
Paint and Stories
Free drawing on a blank canvas, plus picture books read aloud from start to finish.
