Discovering Perimeters

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 rectangles,...

Students investigate area and perimeter of various shapes.  In this area and perimeter of various shapes lesson, students record how area of shapes change when a dimension is doubled, halved, quartered, etc.  Students make scatter plots...

High schoolers investigate the concepts of area and perimeter. The lesson uses a legend to create a context for the proposed word problem. They use the skill of estimation in order to create an ox skin that is found in the story. 

Enough stuffed crust to go around. Pupils calculate the area and perimeter of a variety of pizza shapes, including rectangular and circular. Individuals design rectangular pizzas with a given area to maximize the amount of crust and do...

How many sides does that polygon have? Building directly from lesson plan number eight in this series, learners now find the area and perimeter of any polygon on the coordinate plane. They decompose the polygons into triangles and use...

Strive to think outside of the quadrilateral parallelogram. Worksheet includes two problems applying prior knowledge of area and perimeter to parallelograms and trapezoids. The focus is on finding and utilizing the proper formula and...

Students investigate patterns.  In this Algebra I/Geometry lesson, students explore patterns generated by constructing a sequence of similar shapes and finding the perimeter.  Students analyze data, draw conclusions and make predictions...

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

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

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...
