# Area and Perimeter Lesson Plan

## Overview

This activity is intended to assess your 3rd grade students' ability to find area and perimeter of rectangles and squares. Students will be creating a robot using Google Drawing. They will then find the area and perimeter of each piece of the robot. Once they have found the area and perimeter for each shape in their robot, students will calculate the total area and perimeter of the robot. Photo by Eric Krull on Unsplash

# Summary

This lesson is to help students apply what they have learned about area and perimeter in a fun, individualized activity.

- Time frame: About 60 minutes
- Format: Face-to-face, synchronous, virtual, asynchronous
- Authors: Laura Ferguson

# Background for Teachers

This lesson requires the use of technology that will support the Google suite. It will be most successful with one-to-one technology.

To teach this lesson, you will need an understanding of Google Drawings.

You will need knowledge about how to find area and perimeter of individual shapes as well as composite shapes.

The following resources can help you teach this topic.

- "Perimeter Around the Area": https://youtu.be/rSVMrPu0__U
- "Area and Perimeter Song for Kids": https://youtu.be/Tpy09HOkHyI
- "Perimeter for Kids": https://youtu.be/MTSlKifo4js

# Step 1 - Goals and Outcomes

Learning Intentions:

- Students will be able to calculate the perimeter and area of various quadrilaterals.
- Students will be able to calculate the perimeter and area of composite shapes made up of quadrilaterals.

Success Criteria:

- Students will create a robot in Google Drawings.
- Students will calculate the perimeter and area of each individual piece.
- Students will calculate the perimeter and area of their whole robot.

# Step 2 - Planning Instruction

**Student Background Knowledge**

Prior to this lesson, students will need to have an understanding of perimeter and area of quadrilaterals. Students will also need prior knowledge of multiplication.

**Strategies for Diverse Learners**

Depending on students needs/abilities, you could create a template with the robot already built. The student could put in their own measurements, using easier numbers. You might also need to include a multiplication chart for those that are not sure of their mutliplication facts.

For extension, you could have students choose harder numbers to multiply. They could add extra details on their robot, which would also need area and perimeter identified.

# Step 3 - Instruction

*Set boundaries for what measurements students are allowed to set (whole numbers above 2, not all the same number, etc)

*You may want to have your students check off their robot with you to make sure they have followed instructions before they begin calculating their areas and perimeters.

*I would give my students a sheet of paper that will be turned in at the end of the lesson showing all their calculations.

If you are in need of some videos to review area and perimeter before this lesson, there are several listed in the Background Knowledge for Teachers.

- Review how to find area of a rectangle/square
- Review how to find perimeter of a rectangle/square
- Introduce Google Drawings to your students. Demonstrate how to insert shapes, move shapes, resize shapes, etc. You may need to show them how to insert a text box to type in their measurements.
- Depending on the level of your students, you may want to have them share the document with you. This will give you the ability to hop on with your student and help them if needed in real time.

- Teacher should demonstrate how to create the robot using the tools, and placing the measurements.
- Students are going to insert rectangles and squares into their document, creating a robot.
- If desired, students may work in partners.

- They will need to choose their measurements.
- Once they have created their robot, and inserted their measurements, they will find the area of each individual shape by multiplying the length and width of each piece.
- There is a table on the document to help them keep track of their various areas and perimeters. This can also be used as an assessment throughout the assignment to see how they are understanding.

- After finding the area of individual piece, students will find the perimeter by adding the 4 sides.
- After students have found the area and perimeter of each individual shape, they can add each area together to find the total area of the robot.
- In order to find the total perimeter, it is not just adding their perimeters together. They will need to do a separate calculation of the outside edges of their robots to find the perimeter.

Extension:

- For those fast finishing students, you can have them color in their robot using the paint tool on drawings.

Writing:

- Once everyone has completed their robot, have them write a fun narrative story about their robot. Make sure to have them include a beginning, middle, and end to the story with a conflict and solution.

# Step 4 - Assessments

This whole assignment can be used as an assessment. The area and perimeter of each individual shape can be used for formative assessing. While students are working on this part, I would walk around talk to students as they are working. Asking questions on how they found the area or perimeter of certain shapes.

The summative assessment is the overall area and perimeter of the robot, as well as the creation of the robot.
