Unit 6: Add or Subtract: Problem Solving Summary
Students will begin by using models and sketches to solve problem solving situations that involve addition. They will solve problems in which they are combining groups, including some with missing addends. They will use models to help represent regrouping while working the problem solving situations. Students will then move on to solving problems that involve subtraction using models and sketches, and then by writing number sentences. The problems include: combine problems where two quantities are combined to get a total; compare problems where two quantities are compared to find the difference; change problems where one quantity changes by having some added to it or taken away from it; and equalize problems where one quantity is changed to equal another quantity.
