Discovering Perimeters

There's a reason this worksheet is done in groups! Tricky word problems give geometry scholars a challenge as they use prior knowledge about shapes to find the area and perimeter given a few measurements. Students will enjoy discovering...

Young mathematicians explore the concept of maximizing area and minimizing perimeter in this TI-Nspire lesson. This lesson is broken up into two parts. In the first, one tries to maximize the area while keeping the perimeter constant....

Are all the measurements scalable? Pupils work in groups or alone to determine whether figures are similar and find any missing side lengths. Then, they calculate the perimeters and areas of the figures. Finally, using the measurements,...

Learners explore pi. For this circle measurement lesson, students define and identify radius, diameter, circumference, and perimeter. Learners work in groups to measure several plastic lids and record their findings. Students compare the...

Twelfth graders apply perimeter measurement to items found in newspapers and calculate the cost in terms of feet or yards. They share answers and explanations with classmates.

Discover the distance all the way around. The video introduces the concept of the perimeter of a figure. An explanation shows how to find the perimeter of a variety of polygons along with regular polygons. The presentation highlights the...

Young scholars determine how to find the perimeter of a rectangle. In this perimeter lesson plan, students make rectangles of given sizes using a 20" string. They record the the length, width, and perimeter of each rectangle. They...

Discover how to find the algebraic formula for the perimeter of a rectangle through this tutorial. Your algebra learners will be guided towards the thinking steps around this concept. After showing the video, invite your class to model...

Students discover and apply the formula for the area and perimeter of rectangles and squares. They draw the shapes on graph paper and create tables that include their information.

Consider the relationship between side length and area as an input-output function. Scholars create input-output tables for the area of squares to determine an equation in the first installment of a three-part unit. Ditto for the area of...
