Weavable Toys: Basic Shapes Four sturdy basic shape boards: square, circle, rectangle and triangle. The boards are black to create color contrast with white weaving strips. The easiest way to introduce this activity is for children to remove the colorful shapes from the white strips without using the black boards. Next children can practice removing the white woven strips from the black without using the colorful shapes 18 colorful shapes may be woven onto strips as they are woven into the black boards to create designs. Provide simple and increasingly complex models for children to copy. Then ask children to copy each other's model! Photograph the child's product so that the design can be reproduced at a later time.
