Store description excerpt
Grade 9 Math Mastery prepares Ontario students for the province-wide Grade 9 mathematics assessment. It teaches each concept first, then gives 400 practice questions to prove it stuck. Most study apps only test. This one teaches. Learn the concept • 25 guided lessons, one for every topic on the course • Worked examples that reveal one step at a time, so students can attempt the next line before seeing it • Each lesson names the mistakes students actually make, and why they happen • A short check at the end confirms the idea landed Practise until it sticks • 400 questions across all five strands: Number, Algebra, Data, Geometry and Measurement, and Financial Literacy • Difficulty adapts to the student and moves up as they improve • Wrong answers come back automatically on a spaced repetition schedule, timed for just before they would be forgotten • A mistake journal collects everything missed, with step-by-step solutions • A 57-formula reference sheet, plus a quiz mode for memorising it Practise under real conditions • Mini and full mock tests, timed • A full exam simulation: 25 questions, 75 minutes, no hints, with a complete review afterwards • An estimated achievement level after every attempt Keep them coming back • Speed Drill, Survival, Race Mode, and a two-player duel on one device • A new challenge question every day • Streaks, daily goals and 21 achievements See exactly where they stand • Mastery across all 25 topics at a glance • A predicted achievement level, and the specific topics holding it back • Weekly progress reports and an exam-readiness checklist • A parent view, plus a progress summary you can share or email For parents Everything is built around one question: what should they work on next?
