Across
- 4. breaking apart numbers makes multiplication easier (e.g., 7 × 8 = (7 × 5) + (7 × 3))
- 7. a group of related multiplication and division facts (e.g., 3 × 4 = 12, 4 × 3 = 12, 12 ÷ 4 = 3, 12 ÷ 3 = 4)
- 8. adding the same number again and again (e.g., 4 + 4 + 4 = 12 → 3 × 4 = 12)
- 9. a chart that shows multiplication facts
- 10. grouping does not change the product (e.g., (3 × 4) × 7 = 3 × (4 × 7))
Down
- 1. order does not matter in multiplication (e.g., 3 × 4 = 4 × 3)
- 2. counting by a number other than 1 (e.g., 3, 6, 9…)
- 3. a way or method to solve a problem
- 5. a repeated order or sequence in numbers
- 6. the product of a number and another whole number (e.g., 12 is a multiple of 3)
