3 × 7: 21. Skip count by 7 three times: 7, 14, 21.
4 × 6: 24. Array: 4 rows of 6 = 24.
5 × 9: 45. All 5s end in 0 or 5: 5, 10, 15, 20, 25, 30, 35, 40, 45.
7 × 8: 56. Remember: 5-6-7-8 → 56 = 7 × 8.
6 × 6: 36. Square number: same factor times itself.
9 × 4: 36. 9s trick: digits of 9× products always add to 9. 3+6=9 ✓
Commutative property: a × b = b × a. Order does not matter. 6 × 8 = 8 × 6 = 48.
Zero property: Any number × 0 = 0.
Identity property: Any number × 1 = that number.
Distributive property: Split one factor: 7 × 6 = (7 × 3) + (7 × 3) = 21 + 21 = 42.
Doubling strategy: Know a × b? Double it for 2a × b. 5 × 7 = 35, so 10 × 7 = 70.
Array: Rows × Columns = Product. Rotating the array shows the commutative property.
Skip counting by 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90
