WE ARE LEARNING TO: solve problems using compatible number.
WE CAN DO THIS WHEN: we can answer questions like
9 + 5 + 4 - 13 = 5
9 + 4 = 13 so therefor we have 5 left.
9 + 5 + 4 - 13 = 5
9 + 4 = 13 so therefor we have 5 left.
Teacher comments: Cheryl, I only had to show you how to do this strategy a couple of times and you are able to work on problems like these with confidence. Well done.
