Commutative Property = the order of factors does not change the product.
So 3 x 4 = 4 x 3 will both equal the product of 12!
Associative Property = the factors can be grouped in different ways and still create the same product.
(7 x 2) x 5 = (2 x 5) x 7 will both equal the product of 70!
The biggest KEY is for kids to learn their basic Multiplication Facts with good Fluency then they can start applying these cool Strategies....
PARTIAL PRODUCTS Strategy:
364
x3
12.........4 x 3 = 12
180.......60 x 3 = 180
900.....300 x 3 = 900
1,092
BREAKING UP NUMBERS Strategy:
12 x 30 = ______
(10 x 30) + (2 x 30) =
300 + 60 = 360
LATTICE Strategy or a.k.a. BOX WINDOW Strategy is SO cool, but you need to watch the video to understand this alternative to "Traditional Long Multiplication" like 37 x 54 = ?
