Geoboard

Description

This interactive Java applet simulates the Geoboard manipulative and allows users to explore many shape and measurement concepts. Users create shapes by placing bands on pegs. Options include color fill of shapes and display of perimeter and area measurements. Five suggested activities are included emphasizing understanding of perimeter and area. Other uses are suggested for teachers and parents.
