Learning that a × b = b × a
The commutative property of multiplication means that changing the order of factors does not change the product.
3 rows of 4 dots = 12 dots
4 rows of 3 dots = 12 dots
Pay attention: In the first case, we have 3 rows of 4 dots (3×4 rectangle), and in the second - 4 rows of 3 dots (4×3 rectangle). The number of dots is the same (12), but the arrangement is different!
Choose two numbers and verify that their product does not depend on the order of factors.
Think of three pairs of numbers and write their products in both orders.
