Computing Perimeters of Rectangles

Young mathematicians build an understanding of area and perimeter with their own two hands in a series of interactive geometry lessons. Through the use of different math manipulatives, children investigate the properties of...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry lesson. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden...

Cover some serious area in your geometry curriculum with this collection of worksheets. After first introducing the concept of area using the tiling method, this resource continues on to teach learners how to use...

Around and in—take a different look at rectangles. A portion of a basic geometry playlist discusses the area and perimeters of rectangles. Using the formulas, the presentation works perimeter and area examples with rectangles and squares.

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Follow this engaging slide show on the calculation of polygon perimeter with some hands-on measurement of perimeters to solidify the concepts. On this webpage there are interactive assessment questions and links to related resources by...

Use perimeter and angle measures to practice solving equations. Pupils see two geometry applications of solving two-step equations. The video works one example involving perimeter and two with the sum of angles in a quadrilateral and a...

[Free Registration/Login may be required to access all resource tools.] Students watch a video overview on how to find the area and perimeter of a rectangle.

The teacher illustrates a diagram to help you learn about perimeter. First, she adds the sides together to get the perimeter. Then, she shows how to use the perimeter formula to make it a bit simpler.
