How do you know how many strawberries Lilly and Zim have?

In this lesson you will learn how to solve two-step word problems by making a model.

Let’s Review We need to do all the parts of a two-step problem. Lilly and Zim had 12 strawberries. They ate 7 of them. Their teacher gave them 5 more strawberries. How many strawberries do they have now? Lilly and Zim had 12 strawberries. They ate 7 of them. Their teacher gave them 5 more strawberries. How many strawberries do they have now? There is more than one step to complete the problem.

Core Lesson What information do we know? Lilly and Zim had 12 strawberries. They ate 7 of them. Their teacher gave them 5 more strawberries. How many strawberries do they have now? 12

Core Lesson 12 Then what happens in the story? Lilly and Zim had 12 strawberries. They ate 7 of them. Their teacher gave them 5 more strawberries. How many strawberries do they have now? =5 Do we need to add or subtract?

Core Lesson 12 How many strawberries do they have now? Lilly and Zim had 12 strawberries. They ate 7 of them. Their teacher gave them 5 more strawberries. How many strawberries do they have now? = =10 Do we need to add or subtract?

Core Lesson = Lilly had 10 berries. Zim gave her some more. Now she has 17 berries. Then they ate 6. How many strawberries do they have now? Lilly had 10 berries. Zim gave her some more. Now she has 17 berries. Then they ate 6. How many strawberries do they have now? Do we need to add or subtract? 10 + ? = 17 Let’s find out what happened the next day.

Core Lesson = Lilly had 10 berries. Zim gave her some more. Now she has 17 berries. Then they ate 6. How many strawberries do they have now? Do we need to add or subtract? =11

How did you know how many strawberries Lilly and Zim have? We made a model that followed the whole story.

In this lesson you have learned how to solve two-step word problems by making a model.
