Third graders are challenged to draw their own rectangles given a specific area or perimeter. There are no examples of how each rectangle should look, so it is important for learners to persevere in finding a solution. There is more than...

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

A more challenging set of worksheets, third graders are required to measure area by counting whole and partial unit squares. Students will realize that two partial blocks make up one whole block. Each shaded figure is on a square unit grid.

Third graders simply count the square units that make up each figure in order to find the area. Remind the class to count carefully in order to find the correct answer.

Third graders measure area by counting unit squares inside a rectangle.

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. 

Give small groups handfuls of unit cubes and then dare them to build as many rectangular prisms as possible using only 12 cubes. This engaging activity serves as an introduction to the volume of solid figures. In addition to volume,...

Learners calculate the perimeter of rectangles and squares. They imagine trying to build a fence around a yard or trying to determine how much paint they need to paint a room. They also develop formulas and procedures for determining the...

Make the connections between area, tiling, and multiplication. A performance task and associated unit presents the concept of area and makes the connection to multiplication. Pupils work through three major sections of instruction that...

Paste this resource into your lesson plans like you'd paste a tile onto a mural. Given a diagram of a tile mural with rectilinear figures, future artists determine the perimeters and areas of the figures. They must then develop their own...

Area is a two-dimensional measurement for a two-dimensional figure. The introduction of area expands on the idea of the one-dimensional measurement of length, but instead of staying one-dimensional, it goes in two directions. The video...

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

Reinforce math vocabulary instruction with a set of flash cards. Fifty-six cards offer either a bold-face word or a picture representation equipped with descriptive labels. Terms include centimeters, gallons, square units, and more!   

Explore surface area and calculate how much wrapping paper one needs to cover a whole box with this math video. The resource gives a nice visual of surface area and explains the use of a square unit.

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

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

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...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

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,...

Gardening geometers construct the formula for the area of a rectangle by viewing a video revolving around two young people, their lawn mowing business, and their need to charge by the square meter. A relevant real-life application lesson!

For each of these eight rectangles, scholars write out the multiplication sentence to find the area given the side measurements. They use an example for reference and must remember to include square feet in their answer. All measurements...
