Yasmin blew us away yesterday, when she used an open number line to solve the following problem:
452 = n + 323
Her strategy was awesome and she was able to show and explain her work! Good mathematicians can always defend where they got their answer!
Nancy, Francisco, and Alaina did a great job showing their work on the following word problems. I like how they used numbers and words to explain their thinking! Can you aspire to make your work like theirs? What strategies can you borrow from these learners?
