# Lesson 13

Solve Take From Story Problems

### Lesson Purpose

### Lesson Narrative

In previous units, students solved Take From problems with the Result or Change unknown. In this lesson, students solve a new problem type, Take From, Start Unknown. This type of problem is often challenging for students as the language signifies subtraction, but you must add to solve the problem. Students consider how a drawing represents different Take From story problems. Students are not required to master this type of problem until grade 2.
