Geoboard by The Math Learning Center

What Is It?

The Geoboard 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.

How It Works

Drag and drop a band onto the board.

Drag from a line to create a new vertex.

Drag a vertex from one peg to another.

Tip: Double-click to delete a vertex.

Start over. Clears all the bands from the board.

Fill or Unfill the selected shape.

Fill or Unfill all the shapes on the board.

Delete the selected shape.

Switch between the 5 x 5 peg board and the 15 x 10 peg board.
