Dear Parents and School Community, we have just completed a 7 week intervention focusing on building skills in mental computation between 1 and 100. The children have learned many strategies to help their addition and subtraction. See the photos of their shared strategies and three students who designed their own +/- board game based on their learning. Have fun with at home too with mental addition/ subtraction and try these 64 +32, 58-25, 40+25, 90-27, 57+26, 84-36, 75+29, 94-17, 53-27, 49+21.
