Unit 2, Lesson 27-- Exploring Area of Rectangles

Lesson 27- Exploring Area of Rectangles

Introduction

Hello Mathematicians! Today we will use geoboards to continue to build rectangles and explore their area.

Part 1 Directions:

  • In the interactive below, choose the square geoboard.
  • Practice building your own rectangles and determine the area of each by counting the number of squares that would fit inside.
  • Write a multiplication equation in your math notebook that includes length, width, and area in square units.

Part 2 Directions:

Directions:

  • Open the interactive drawing assignment below, and make a copy.
  • Use the tiles to measure the rectangles in square units.

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.)

Wendy and Wendell each have some equal size square stickers that they arrange into an array on the covers of their math notebooks. Wendy makes a 6 by 5 array.  Wendall makes an array that is 3 by 10.  Who has the bigger area covered on their notebook?  How do you know?

D (Draw a picture.)

W (Write and solve an equation.)
