Accompany a physical Geoboard or use this printed 5x5 Geoboard paper with lines for writing to explore and explain basic geometric concepts.

Geoboards can take up a lot of space in the classroom; instead use this 5x5 geoboard paper! Six geoboards and lines for writing are included in this multi-use printable and template. 

Don't be a square! Help your budding mathematicians discover patterns within squares. Scholars create squares on geoboards and identify patterns in the number of nails, both nails on the edge of the squares and nails within the squares....

Young mathematicians build an understanding of area and perimeter with their own two hands in a series of interactive geometry lessons. Through the use of different math manipulatives, children investigate the properties of...

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

Stretch your knowledge of ratios to the coordinate plane. The interactive allows pupils to set the endpoints of a directed line segment and form a right triangle. Using rubber bands, users visualize the line segment divided into equal...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

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...

Use this virtual geoboard to explore the attributes of various polygons. This would work well on an interactive whiteboard.

Students can use the interactive geoboard to create different types of quadrilaterals and investigate the properties of quadrilaterals. Requires Java. The geoboard can also be downloaded for offline use.

Warm up and exercises using a geoboard.

This activity could be used to introduce the concept of congruence. You will need the following materials: geoboards, rubber bands, and geoboard recording paper.
