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.
