Place rubber bands on geoboards to create shapes like polygons, triangles, rectangles and hexagons. Have students find the perimeters and areas of those shapes.
Ask students to form shapes with one corner at a certain pair of Cartesian coordinates.
Ask students to flip and move shapes using the geoboard. They can create a shape, such as a triangle, out of rubber bands and then flip that triangle across the X- or Y-axis, noting how the triangle's coordinates change.
Give the students values of slope to graph on their geoboards. The students will create rubber band lines matching the given slope.
Have the students create their own rubber band lines and determine the slopes of those lines.
