How can you use a number line to help you multiply?
I can skip count on a number line to help me multiply.
What is the commutative property?
The commutative property sates that two factors in a multiplication equation can be moved and the product will remain the same.
Lilly has 3 food bowls. Each food bowl has 10 kibbles. How many kibbles can Lilly eat today? Write the multiplication equation and answer. Use one strategy to solve.
Lilly can eat 30 kibbles. 3X10=30, or three equal groups of ten is thirty.
