The unit of area on the geoboard is the smallest square that can be made by connecting four nails: We will refer to this unit as 1 square unit. On the geoboard, the unit of length is the vertical or horizontal distance between two nails. Perimeter is the distance around the outside of a shape and is measured with a unit of length. Geoboard Math Playground. A red band has been placed on the board for you. To create more shapes, drag a band from the tool bar to the board. Use the color palette and fill tools to change the way the band appears. Write on the board with the pen tool. Erase part or clear all. The Geoboard app is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around the pegs to form line segments and polygons and make discoveries about perimeter, area, angles, congruence, fractions, and more. Geoboard Easily stretch bands around pegs to explore geometric and other math concepts. Choose rectangular or circular grids in either small or large sizes.

What are Geoboards?
Developed by Egyptian-born, English mathematics scholar Caleb Gattegno, Geoboards are a tool used to teach children geometry. They were originally created as wooden squares with nails or brass pins in a variety configurations, upon which rubber bands could be stretched into various shapes.

Why should I use them?

Geoboards provide students with the experience of creating shapes, rotating shapes, exploring angles, and concretely exploring the properties of geometric objects.
Virtual geoboards in particular have a very practical benefit of avoiding the use of actual rubber bands that can be a distraction in the classroom. In her discussion of the first time she used geoboards in the classroom, veteran teacher Marilyn Burns shared this funny story:
Gee Board
“I gave a geoboard to each student, distributed a cup of rubber bands to each pair, and gave time for exploration. Within a minute, chaos reigned. The cups were empty; every geoboard was full. Some students slouched in their chairs waiting for instructions. A few strummed the rubber bands as if the geoboard were a guitar. Several students, attempting to remove rubber bands from the geoboards, instead sent them flying. Others disappeared under their desks to retrieve lost rubber bands. This wasn’t what I had envisioned.”
