Students 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,...

Pupils practice a variety of strategies with varying numbers of tiles to form shapes and then find the minimum and maximum perimeter for each one. Each group is assigned a different area to build either with square tiles or a geoboard....

Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle activity, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

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...

Eighth graders plot points and investigate polygons. They locate a point, using ordered pairs of integers on the coordinate plane. Students compare geometric measurements and computations on coordinate axes as they are applied to...

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.

Pupils calculate area using the geoboard application on their calculators. They use a TI-73 calculator to find the areas of the shapes provided in the accompanying worksheet. Screen shots and instructions for creating shapes in the...

Third graders recognize geometric shapes with acute angles, make geometric shapes with acute angles on geoboards, and draw acute angles on geopaper.

Young scholars explore geometric vocabulary through creation of shapes on a geoboard. They present design attributes, transfer of design, and color-coding components mix to create a fun and exciting lesson that stretches student thinking.

Students review angles, sides, and properties of basic shapes. Using a geoboard, they make as many different tirangles as possible.

Fourth graders examine halves of a whole and discover through activities that they must be exactly equal in size. Working with Geoboards and Dot-Paper Squares, the class practices finding halves that are both congruent and incongruent.

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.

Learners manipulate shapes to find multiple lines of symmetry. They use color to visualize the lines of symmetry.

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Third graders demonstrate their mathematical knowledge of symmetry and reflection using congruent geometric shapes while working as an artist and mathematician looking at a medieval-styled stained glass window.

Eighth graders explore congruent and similar figures.  In this eighth grade geometry instructional activity, 8th graders use geoboards to create congruent and similar figures and explore the relationships between the sides and...

Fifth graders manipulate and draw shapes to demonstrate the concept of flips, slides, and turns using letters and arrows on graph paper.

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 calculate the perimeter and area of given figures and lengths.

Fifth graders work with polygons.

Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

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...
