If Amy had 3 cats and each one had 4 legs, how could we find how many legs all the cats had?

Page 3: Multiplication 3 x 3 = 9 4 x 8 = 32 1 x 6 = 6 6 x 5 = 35.

=4 legs

=4 legs

=4 legs

=12 legs

Another way to figure out the answer is to multiply. Multiplication is a fast way to add equal numbers. Since all 3 cats have 4 legs, instead of adding them together, we could multiply.
