Description

Does your child breeze through math facts but freeze the second a word problem appears? You're not alone, and the problem isn't arithmetic. It's recognizing what kind of problem they're looking at. Problem Detective teaches kids 8-11 the six word-problem structures that researchers say unlock everything: Join, Separate, Compare, Equal Groups, Part-Part-Whole, and Multiplicative Compare. Instead of guessing whether to add or multiply, kids learn to spot the pattern first, then solve with confidence. How it works: - Cartoon scenes pre-teach each schema in plain language - Signal words are color-coded so kids see the clues - Drag-and-drop sorting builds pattern recognition - Visual diagrams let kids map the problem before doing any math - A vocabulary garden unlocks illustrated math words as they play Designed with neurodivergent learners and English language learners in mind: short sentences, visual supports, and zero time pressure. No accounts. No ads. No data collection. Everything runs on the device. One-time purchase includes the full Grade 3 curriculum. Optional expansion adds Grade 4-5 multi-step and fraction schemas.
