Crack the case of every word problem. Problem Detective teaches the secret most math classes skip: every word problem is one of six types.
LEARN THE 6 SCHEMAS
Join, separate, compare, equal groups, and more - each problem type introduced with a quick, friendly scene.
DETECTIVE CASES
Sort each mystery problem into the right bin, then solve it. Closer to a game than a worksheet - and it builds the exact skill tests reward.
THE VOCABULARY GARDEN
Every cracked case grows a new math word. Watch the garden fill as confidence blooms.
KID-SAFE BY DESIGN
No ads, no internet, no accounts - gentle music, everything on this device.
