High schoolers design a cafeteria floor plan. In this area and perimeter lesson, groups create an efficient lunchroom layout on poster board by using geometric shapes and formulas as the basis for their designs. In the accompanying...

Students explore the concepts of length, perimeter and area. Students develop an understanding of length, perimeter, and area. Students calculate the area and perimeter of random shapes and calculate the area and perimeter of a triangle...

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Learners use shapes and manipulatives to demonstrate patterns. In this patterns lesson plan, students also break up patterns to identify a pattern unit.

Learners study facial symmetry. They explore lines of symmetry, and create illustrations with multiple lines of symmetry.

Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

This is a nice hands-on activity where young geometers create trapezoids and calculate their area by looking at areas of quadrilaterals and triangles. 

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

In this consumer mathematics activity, students explore a variety of topics in mathematics including simple interest, perimeter, area, volume, translating words into symbols, percentage problems and mortgage calculations. The fourteen...

Second graders describe a polygon in the form of a riddle.

In this geometry learning exercise #13 learning exercise, 10th graders work in groups to solve 6 geometry problems, involving measurement of angles.

Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

Sixth graders explore characteristics of two and three-dimensional figures. They observe the teacher demonstrate the faces, edges, vertices and names of specific figures. In groups, 6th graders examine and describe given figures. ...

In this game students move around a game board by spinning a spinner and moving to the next place on the board whose shape matches the one they spun.

Students construct a three-dimensional model of the Pantheon.

Students learn the difference between perimeter and area by watching a video and a hands on activity.

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Young scholars explore symmetry. In this geometry lesson plan, student identify and define bilateral symmetry, radial symmetry, pentagonal symmetry, hexagonal symmetry, and cubic symmetry. Students construct examples of these types of...

Students examine the built environment and infrastructures of their community by constructing contour equipment, using the equipment, and comparing their results to current topographical maps of the same area

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Eighth graders continue their geometry unit by focusing on volume. Using data, they create a spreadsheet, estimate and calculate volume. They solve real-life problems and round their answers to the hundredths place. They also practice...

In this transformations worksheet, pupils draw the transformations of the triangles and parallelograms in graphs. They complete four drawings.

Students design a rectangular box without a lid that has the largest possible volume using the supplied sheet of centimeter graph paper. They work in groups to construct different size boxes to determine the largest possible volume and...
