This beloved Montessori material from the Sensorial area of the curriculum inspires such creativity! Geometric discoveries abound! But what a nightmare to sanitize! If your kiddos love cutting, why not use this? They can cut, design and paste what they make. There are the traditional red, yellow, green, gray and blue colors as well as a blank template for children to color as they please as well or make your own new set in outrageous and delightful colors!
