1. How do you solve a problem that has more than one step? For example: At the pet store, there are 134 birds, 55 cats, and some dogs. If there are 395 animals in all, how many dogs were in the pet store?

2. In this lesson you will learn how to solve a multi-step problem by drawing a bar model.

3. Let’s Review Understand the problem Who and What Chunk and Draw Compute Check Model Drawing Steps

4. A Common Misunderstanding Key Words in all left altogether difference fewer how many fewer

5. At the pet store, there are 134 birds, 55 cats, and some dogs. If there are 395 animals in all, how many dogs were in the pet store? All I have to do is add!

6. A Common Misunderstanding All I have to do is add! I understand the whole problem. 134 + 55 + 395 = ? 134 + 55 + 395 = 584 There are 584 dogs in the pet store.

7. Core Lesson At the pet store, there are 134 birds, 55 cats, and some dogs. If there are 395 animals in all, how many dogs were in the pet store? There were dogs in the pet store.

11. Core Lesson Animals in the pet store birds cats dogs 395 134 + 55 + ? = 395 134 + 55 + ? = 395 9 80 100 + + = 189 395 - 189 = 206 ? 134 55 206

12. Core Lesson Animals in the pet store birds cats dogs 395 134 55 206 134 + 55 + 206 = 395 There were 206 dogs in the pet store.

13. Core Lesson 134 + 55 + ? = 395 980 100 + + = 189 395 - 189 = 206 Animals in the pet store birds cats dogs 134 55 206 395 Try to solve it a different way!
