Jump into equivalent fractions using these fun scenarios for mathematicians to solve. First, they use geoboards to find different ways to divide a rectangle in half. Then, an alien from the planet Fractional is after one half of their...

Young mathematicians calculate the area of rectangles and squares. In this geometry lesson, learners are grouped in pairs and use geoboards to construct rectangles. They calculate the area of the figure by counting the number of square...

Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...

Students 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 (and...

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson plan series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

 For this geometry lesson, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Young scholars work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the lesson. In part two, students use geoboards to construct polygons, look for patterns, and find a general rule.

Sixth graders use geoboards and dot paper to experiment with geometric concepts. For this geometry lesson, 6th graders complete four activities using geoboards or dot paper including naming points on a coordinate plan and finding the...

An outstanding lesson on teaching the basic shapes and polygon names to young geometers is here for you. In it, learners investigate the role of basic polygons in the strength of structures. They use geoboards, rubber bands, streamed...

Students describe shapes to their classmates using specific properties and practice making triangles on geoboards. In this geoboards lesson plan, students use string on the geoboards.

Geometers calculate the area of plane surfaces using the formulas for the area of a square, rectangle, and triangle. They develop the formula for calculating the total surface area of two geometric solids: the cube and rectangular prism.

Middle school geometers determine the area of a shape on a geoboard or dot paper and draw figures that meet given area conditions. Working as a class, they develop and discuss various ways to draw geometric shapes with specified...

Using geoboards, computer programs, and hands-on manipulative materials, elementary schoolers engage in a study of two and three-dimensional geometric shapes. This lesson is chock full of good teaching ideas on the subject, and the...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.

First graders create two-dimensional shapes. For this shapes lesson, 1st graders learn about different two-dimensional shapes. Students have many hands-on experiences with these shapes including the use of geoboards, shaving cream, yarn,...

Second graders create a shape garden. In this polygons lesson, 2nd graders practice making shapes using a geoboard and read the book The Greedy Triangle by Marilyn Burns.  Students also design a shape garden using construction...

Fifth graders will use geoboards to construct parallelograms. They will determine the area of a rectangle and then apply that thinking to determine the area of a parallelogram. Note: The format of this lesson is much like a PowerPoint,...

Third graders begin learning about multiplication using arrays. In this multiplication with arrays lesson, 3rd graders interact with tiles on the overhead as they follow the teacher in making arrays. They write multiplication sentences...

Pupils create enrichment activities for Geoboards, Napier Rods, and Bean Sticks. This includes annotated links to problem solving Internet Sites.

Third graders create art using shapes. In this shapes and patterns instructional activity, 3rd graders explore multiple ways of combining shapes to create new objects and art.

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.
