Math Facts Mastery — Practice App (Grades 1–6)
Most students who struggle with math aren't missing understanding — they're missing fluency. When a student has to stop and work out 7 × 8 in the middle of a long division problem, the procedure falls apart. Fact fluency is the foundation, and this app builds it the right way.
Math Facts Mastery works through all four operations — addition, subtraction, multiplication, and division — using a method proven to actually stick. Your student works on a small set of facts at a time (three by default). A fact is mastered after three correct answers in a row. The moment one fact is mastered, one new fact takes its place — so the student is never overwhelmed, never bored, and always making progress.
Facts are introduced in teaching order, easiest patterns first. Mastered facts quietly return for review — miss one and it comes back into practice until it's re-mastered. An optional fast-recall timer can be turned on once accuracy is solid, building the speed that makes fluency automatic. Multiple students can each have their own profile.
A placement test lets students skip ahead past facts they already know, so no one wastes time on 0s and 1s they mastered years ago.
