Perimeter and Area of a Square

Activity Overview

Students study the perimeter and area of a square, and explore the relationship between them and the length of the side of the square.

Before the Activity

Install the Cabri™: Jr. App on the students' graphing calculators using one of these two methods:

TI-Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable

TI-Navigator™ "send to class" feature

See the attached PDF file for detailed instructions for this activity

Print pages 69 - 70 from the attached PDF file for your class

During the Activity

Distribute the pages to the class.

Follow the Activity procedures:

Use the Regular Polygon feature on the calculator to construct a square

Measure and record the length of one side of the square

Measure the perimeter and area of the square

Alter the square until its side length is 1 cm and record the values of perimeter and area in a table

Record the side length, perimeter, and area of squares with side lengths of 2, 3, 4, 5, and 6cm

Observe that the perimeter of a square increases by 4 units as the length of the side increases by 1 unit

Compare the first six perfect square numbers to the numbers in the Area column

Observe that the area of a square is always a perfect square number

After the Activity

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
