Unit 5, Lesson 1-- One Step or Two Step?

Lesson 1-- One Step or Two Step?

Introduction

Hello Mathematicians! Today we will look at story problems that have more than one step that must be completed to solve them.

First, put together this dot pattern image.  What do you notice? What do you wonder?

How can we find the total number of dots without counting each one?  Open the interactive slide deck below, and make a copy.  Follow the directions on how to show your thinking.

In Your Math Notebook:

Let’s get out our math journals and  work through the following application problem. Make sure you read the problem carefully, draw a picture to match your thinking and write and solve an equation.

Read, Draw, Write. DONE!

R (Read the problem carefully.) Kelly had 20 cookies. She baked 12 more. Then her family ate 5 of them. How many cookies were left?  D (Draw a picture.) W (Write and solve an equation.)
