# Lesson 15 Problem Solving with Line Plots

• Let’s solve problems using a line plot.

## Warm-up Number Talk: Multiply by 18

Find the value of each expression mentally.

## Problem 1

Your teacher will give you either a problem card or a data card. Do not show or read your card to your partner.

## Activity 2 Mathematical Questions

This line plot shows the weights of some apricots that Mai picked.

1. What fraction of the apricots weigh less than ounces? Explain or show your reasoning.

2. Write a multiplication equation that represents the total weight of the apricots that each weigh ounces.

3. Do all of Mai’s apricots together weigh more or less than a pound? Explain or show your reasoning.

## Problem 1

Han is making a line plot of the seedlings his class grew. This is what he has done so far.

Use this information to complete the line plot. Explain or show your reasoning.
