Students explore a variety of strategies to solve story problems in the classroom for both addition and subtraction. Students were grouped, given a problem, individually they solved the problem, then shared their thinking with their group. Activities like these, give the students opportunity to revise their thinking after talking with their group! Revising one's thinking is a life skill that students practice daily in the classroom by talking about what they know, listening to their peers, reflecting on what their peer said, then they decide to revise their thinking or help coach their peer to revise their thinking.
