A Way to Solve Multiplication and Division

By Dash

In fourth grade we have been doing multiplication and division. We use arrays to help us while doing our work. We show our work on the board.  Problems like 6 x 5 are easy and fun. We have studied our combinations up through 12 x 12. When we get a harder problem we are learning new ways to solve them.

In the picture below, Tara wrote down my work in red. I didn’t know this by heart at the time so I did 13 x 4 which is 52 and then I did 52 x 2 which is 104. I knew I needed to double 52 to get to 104 because 4 is half 8.
