This document walks students through a step by step process for solving the multiple subtype problems identified by the Progressions. This helps teach students about the types of problems there are as well as to identify the part-whole relationship within the story problem. After setting up their story problem representation with a written statement and a tape diagram, students can then choose an appropriate strategy to solve the problem. There are 3 of the same problem with each subset so that students can see the relationship between what they are looking for within the different subset types. There is also a notes page on how to use this document and what questions to ask.
