The Almost-Right Lab

Train a mistake-making creature by finding, explaining, and correcting common math errors. You're the coach. The creature is almost right — and needs your help.

6.AT.C.8 · One-Step Equations
Teacher Note: The Almost-Right Lab is organized by common misconceptions, not lesson order. Each mission targets one specific wrong-thinking pattern your students may have. Use this lab after direct instruction on inverse operations, or as a pre-test review. Students work as coaches — they diagnose the creature's mistake, teach the rule, and check the fix. No accounts needed. Progress saves on this device.
