Perimeter

Get into springtime with a festive practice sheet designed to test scholars' knowledge of grids. Learners locate items such as watering cans, snails, and flowers following the x and y-axis. Worksheet themes include Earth Day, gardening,...

Does a shape's perimeter always match its area? Learners approach this and other claims in this shape investigation learning exercise. Using blank grids, they draw various shapes based on required perimeter and area measurements,...

Given a rectangle with specified dimensions, learners are prompted to create a new rectangle with the same perimeter, but a different area. This challenges third graders to think about perimeter and area in a new way. Each problem...

What a great assessment to give young mathematicians in order to test their knowledge on two- and three-dimensional shapes. Learners name various shapes, identify the number of edges, faces, and vertices, match an unfolded version of a...

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,...

A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different area...

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...

What a fantastic resource! The class practices finding the area and perimeter of various regular and irregular shape by first counting the grid squares inside each shape, and then by using the traditional formula. The process is fully...

A few good questions move this lesson right along. Young mathematicians use critical-thinking skills as they learn how to determine the perimeter of various shapes. They determine perimeter first by measuring and adding the lengths of...

Third graders determine the perimeter of a shaded section by counting the number of unit squares that surround it. Each section is shaded on a small square unit grid.
