Sixth graders investigate surface area.  In this surface area lesson, 6th graders design a box of candy that has a volume of 30 cubic inches.  Students are trying to minimize surface area while keeping volume constant. ...

First graders find angles in their classroom. In this geometric figures lesson, 1st graders identify, describe and classify angles they see in their world. Students create pictures that contain angles and display them in the room.

Third graders recognize and identify geometric shapes, work with manipulatives to reinforce understanding, and create polygons with various angles to display their knowledge of the different types of angles.

Students identify lines of symmetry.  In this symmetry instructional activity, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of...

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.

First graders investigate symmetry in patterns by utilizing unifix cubes.  In this pattern lesson, 1st graders practice creating patterns that are perfectly symmetrical no matter which way it's looked at.  Students utilize...

Learners examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

Fourth graders explore how to find the area of a rectangular object. As a class, they discuss definition of area and strategies for finding area. The teacher models finding the area of an object by counting squares. Students observe...

Students discover building plans and practice reading measurements.  In this architectural design lesson, students investigate the areas of the specific World Trade Center locations that need to be rebuilt and determine the cost....

Learners practice finding the areas and patterns within a square and explore the concept of quadratic functions. They observe and record the area values in a table, plot a graph of Area versus Distance and complete a variety of student...

Fifth graders, after seeing Honeycomb examples, complete a Classifying Angles worksheet, Clock worksheet, and Defining Angles worksheet.

Fifth graders work with polygons.

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

First graders draw and describe various types of polygons. they investigate their own environments for examples of polygons. After reading the book, The Greedy Triangle, they discuss everyday objects that are polygons. They create shape...

Students are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Math Forum provides a set of links to sites that are related to geoboard activities. There are several great links to lessons using geoboards. The links provide insight into how to use them, including how to perform various measurements...

This site is a lesson plan for using a geoboard in a sixth grade geometry class. The lesson serves as an introduction to the geoboard and its uses in geometry. Some topics the lesson covers include helping to visualize shapes and and...

Lesson plan where students learn about congruent and similar figures by viewing models and by using geoboards, pattern blocks, and the Internet. (Note: Lesson cited in the procedures cannot be found at the link provided.)

This collection of five middle school math lessons covers the topic of plane geometry, specifically the concept of slope. The first lesson introduces students to plotting points on a Cartesian grid using a Geoboard. Lesson two moves them...
