# Lesson 13 Represent Story Problems

• Let’s compare representations and solve problems.

## Warm-up Notice and Wonder: Compare Representations

What do you notice? What do you wonder?

## Activity 1 Card Sort: Represent Stories

Today we are going to think about how we can use diagrams to make sense of stories and use number lines to show our thinking.

## Activity 2 All Kinds of Representations

Solve each problem. Show your thinking. Use a number line or diagram if it helps.

1. Clare started with 24 cubes and added on some more. Clare made a train with 42 cubes. How many cubes did Clare add on?

2. Andre had 37 cubes. Then he added 39 more to make the train longer. How many cubes did Andre use?

3. Mai wanted her train to be 55 cubes long. So far she has 47. How many more cubes does Mai need?

## Problem 1

There are 18 students in the classroom. Then 13 more students join them.

1. Label the tape diagram to match the story.

2. Label the number line to match the story.

3. How are the tape diagram and number lines the same? How are they different?

4. How many students are in the classroom now?
