Third grade is the year multiplication takes center stage — and the year many kids either build confidence or fall behind. Lumi's 3rd grade math curriculum teaches each times table with a strategy, not just raw memorization, so facts stick for the long term. Then Lumi puts those facts to work in division, area, and multi-step problems.

My 3rd grader struggles with multiplication. Will Lumi help?
Yes — this is Lumi's sweet spot. Each times table is taught with an explanation of the pattern or strategy (not just drill-and-repeat), then practiced with voice-guided interactive problems. Most kids see significant improvement in fact recall within a few weeks of daily use.
