Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes. This...

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...

Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...

Your geometers are used to finding the perimeter of a square or rectangle, so give them something different this time! With this lesson plan, small groups will receive a picture of a shoreline and calculate the perimeter. The website...

Learners explore perimeter, area and volume. Using geoboards, toothpicks, and marshmallows, students create specific shapes. They are directed to use formulas to find the volume, area, and perimeter of the created shapes. In groups,...

Sixth graders design rectangular gardens with a given perimeter and generalize how to maximize the area Students applying the formulas for perimeter and area of polygons. They analyze length, area, and volume and make relationships...

Youngsters explore visual arts by participating in a geometry identification activity. They read the book The Very Busy Spider and identify the techniques spiders use to create webs. Have you ever noticed that their webs are geometric...

Fourth graders use pattern blocks to explore areas of polygons. They explain that the answers to the area of the same polygon vary according to the units of measurement used. They visualize how different units of measurement can be used...

Fourth graders practice calculating area by creating a classroom quilt. Students are given a 6x6 inch square material they design based on a classroom theme. A sample of the class quilt is created using graph paper so students may...

Get creative juices flowing when you allow groups to figure out a procedure for how to find the area of squares and rectangles. They may use the individual patchwork blocks, or they may design one using the Design Template.

Students create a mini city using proportions that fit a model human they construct using tin foil. They plan the city including a library, sports arena, living spaces, parks and businesses. When constructing the paper buildings, they...

Students measure the perimeter and area of their polygons. In this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...

Students explore a story about a room decoration activity to learn about measurements and area. In this measurement lesson, students listen to a story about a boy who is redecorating his bedroom. Students discuss the story and work in...

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations instructional activity, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become...

Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

Students explore quilting. In this math patterns lesson, students define the perimeter of a quilt border, create tessellations using geometric shapes, and detemine the area of a quilt.

Fourth graders construct squares and rectanges in order to help them find areas and perimeters. They gain an understanding of area and perimeter through teacher modeling and then they construct squares and rectangles.

Young scholars create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base...

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

Fourth graders demonstrate knowledge of the size of a wagon by making several different predictions. They develop a list of items that pioneers would need while traveling on a wagon train.
