How it works
Choose the learner’s current school grade. Start at Level 0, then practice the seven topic levels. If practice feels too hard, try the suggested easier grade.
Questions include diagrams where useful and a Read question control on supported devices. Reading a question aloud does not use a hint or reduce rewards. Help is unlimited and never penalised.
Practice, not assessment
Mathroom makes practicing familiar math into a game. It does not diagnose ability, deliver instruction for a school course, or provide official test results.
Practised skills are mapped to Common Core State Standards for Mathematics codes. The report describes practice coverage of the listed standards, not a formal assessment.
Read the standards mapping and its limits.
