Multiplication lessons for grades 2–4
Children see each multiplication fact as rows and columns of dots. They learn the friendliest tables first (2, 10, 5, then 0 and 1), then 4, 3 and 6, then 9, 8 and 7, and finish with 11, 12 and mixed facts up to 12 × 12. Every problem is read aloud, and a hint walks through the array row by row instead of giving the answer. There are 20 levels.
