Grade 5 · Computational Fluency
Multiplication and Division Facts to 100
Grade 5 targets recall of 2s, 3s, 4s, 5s, and 10s facts. The remaining facts (6s, 7s, 8s, 9s) are built through strategies: doubling (8x6 = double 4x6 = double 24 = 48), near-squares (9x8 = 9x9-9 = 81-9 = 72), and using known facts (7x8 = 7x7+7 = 49+7 = 56). Annexing zeros extends single-digit facts to any power of 10: 6x3=18, so 6x30=180, 6x300=1800. This generalization is the bridge between facts and multi-digit computation.

WHAT STUDENTS WILL LEARN
✓Recall multiplication facts for 2s, 3s, 4s, 5s, and 10s fluently by end of Grade 5
✓Use doubling and halving, annexing zeros, and the distributive property as mental math strategies
✓Apply known facts to multi-digit mental arithmetic: 6 x 30 using 6 x 3 = 18
✓Connect multiplication and division fluency: knowing 7 x 8 gives three additional facts
✓Build toward recall of all facts to 100 through consistent practice and authentic contexts
