A second-grade student solves a variety of addition and subtraction math stories. Using his fingers as math tools, he is able to solve the stories, even as what is known or unknown shifts. Solving a range of problem types encourages children to make sense of the problem and develop flexible thinking. Here, we see the child strategically select a method for solving each story based on the given numbers.
Focus on the Child videos are taken from one-on-one interviews with individual children. The interviews are designed to elicit evidence of children’s mathematical thinking. They are not teaching episodes or formal assessments.
