This Application Problem is a part of the Lesson 21, Unit 7, Grade 3. Scaffold the Application Problem for students working below grade level. One solution path (shown here) is to find half of the perimeter and list all addend pairs with a sum of 7. Set individualized goals for effort and persistence, perhaps by providing a checklist of problem-solving self-talk, such as, "What information do I know?"
