TallytideWhy children keep coming back
Explaining a mistake is one of the best ways to understand maths. Tallytide turns that into a game.
Teach Gloop
Gloop answers with total confidence, and often wrongly. Your child decides if he's right, gives the real answer, and picks the reason he slipped.
Bar models, step by step
Word problems the Singapore way: draw the model, find 1 unit, then answer. Every step is checked, with a clear worked solution.
An island adventure
Sail from Counting Beach to Before-and-After Cove. Each island ends with a Big Quiz, a medal and a souvenir for Gloop.
A look inside
Short lessons, big friendly buttons, and help from Professor Pickle when your child is stuck.
