Yesterday, we had another great math talk! Our mathematician talked us through a challenging division problem. She showed us how she used reverse subtraction, or subtracting backwards, to solve her problem.

Here was our problem: Francisco had 30 soccer balls and 5 sports bags. If he split them equally, how many balls would fit in each bag.

First our mathematician subtracted 5’s backwards from 30. She wrote the equation 30 – 5 = 25, then 25 – 5 = 20, and so on all the way down to 5 – 5 = 0. Next, she counted up how many times she subtracted five of the soccer balls from the original 30. She figured out that 30 can be split by 5, 6 times! So Francisco can put 6 soccer balls into each of the 5 sports bags. 30/5 = 6.

In third grade we love to go home, play with our friends, read books, work on some math, have a healthy dinner, brush our teeth, and go to sleep! But sometimes, we also play video games. Sometimes these games are violent, but we know that the violence is fake and we would never ever put our hands on someone else or use our words to hurt someone. Mrs. Felter doesn’t really love these games. She does love Mario Cart.

This week two of our all-star writers wrote very detailed stories about video games. We are very proud of their hard work!
