Study Notes
Basic Understanding
- A basket with 4 rows of 7 apples each contains a total of 28 apples.
- A garden with 6 rows of flowers, each containing 8 flowers, has a total of 48 flowers. This can be solved using the distributive property (6 x 8 = 6 x (5 + 3)).
Using Arrays
-
The completed equation using the array:
- 3 × 9 = 3 × (5 + 4)
- 3 × 9 = (3 × 5) + (3 × 4)
- 3 × 9 = 15 + 12
- 3 × 9 = 27
-
Splitting 5 rows of 6 desks:
- 5 × 6 = 5 × (3 + 3)
Math Stories
-
Theo has 4 plates with 8 cookies each, for a total of 32 cookies. Using the distributive property:
- 4 × 8 = 4 × (5 + 3)
-
Robin's method of finding 7 × 6 by multiplying 7 × 5 and 7 × 1 makes sense. This is also a form of the distributive property.
-
Solving to check: 7 × 6 = 42
Matching
- 4 × (2 + 3)= 20 (Matches with A)
- 6 × (3 + 5) = 48 (Matches with C)
- 3 × (4 + 6) = 30 (Incorrect match, should be B, but no other option)
