# Geoboard, by The Math Learning Center

by Clarity Innovations

### What is it about?

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.

Old classic, modern twist. Geoboards have been used in classrooms since the dark days of chalk. But this modern twist is a great take on the classic resource. First, you can drag bands over from the bottom of the screen in order to join them between two pegs. The bands always join vertically; to make a horizontal link, you'll need to drag one end over to the left or right.

Choose a different color, mix it up. After pegging one shape, you can add another onto the same board. To differentiate between the two, why not choose a different color? Better yet, choose a different color and create a different shape!

Do you accept the challenge? Geoboard would be great in challenging students to create as many different shapes on one single board. Ask them to choose a different color for each shape (if possible -- after all, there are only five different colors), and set them off working independently. Children could record their work by capturing screenshots of the Geoboard app (see below for more information on how this can be done).

### App Store Description

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.
This virtual version of the manipulative is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPod Touches, iPhones, or iPads.

FEATURES

• Create line segments and polygons by stretching bands around the Geoboard’s pegs.

• Choose from 5 different band colors; 8 band colors on the iPad.

• Fill individual shapes with a transparent color, or use the Fill All button to toggle all the bands between filled and unfilled.

• Switch between the standard 25-peg square board, a rectangular board with 150 pegs, or a circular board with 13 pegs. The circular board enables explorations with angles, fractions, and time measurement.

• Duplicate shapes then move, rotate, or flip them to explore symmetry and congruency.

• Change the color of selected bands.

• Display grid lines with or without numbering to more easily calculate area and identify shape locations.

• Use the drawing tools to annotate work and show understanding

• Write equations and expressions with the text tool.
