Introduction to Multiplication


Hello Third Grade Friends!

I have been playing Loops and Groups with my friends. We draw loops. Then we draw the same number of objects in each group. I used to add to find how many in all. Now I know I can multiply by thinking about groups.

How many stars are there in all?

1 group of 3 yellow stars. 1 group of 3 orange stars. 1 group of 3 red stars. 1 group of 3 purple stars.

3 + 3 + 3 + 3          4 groups of 3          4 × 3

Your friend,
