A
cluster is a smaller
multiplication problem or fact that can be put together with another
multiplication fact. This will create or
prove a product to a bigger problem.
I know that 23 can be
split up into 20 + 3. I can take two
clusters to prove this product. (20 X 5=100) + (3 X 5=15). 100 + 15 =115, so 23 x 5 equals 115.
DIRECTIONS: Create a cluster to get or prove the product
of each multiplication problem. FOR
EXTRA CREDIT: Create two different clusters for the problem.
