This brand new set of outlined 3" geometric foam stamps that matches our existing solid geometric foam stamp set is also a great way to teach shape recognition, increase geometric understanding, and teach grouping. These durable, high density foam stamps are easy to clean and a picture on top makes the image easy to align. This set is great to use with our paint or ink pads. The set includes a hexagon, a kite, a triangle, a rectangle, a pentagon, a rhombus, a trapezoid, an octagon, a square, and a circle.
