This interactive adaptive book explores six basic two-dimensional (2D) shapes and asks the student to sort the shapes from smallest to largest. Shapes included are triangle, circle, square, rectangle, rhombus, and hexagon. This resource is 8.5" x 11" and there is space on the left side for binding. Round velcro dots are ideal to adhere the shapes to each page and the life of the book can be extended if printed to cardstock and laminated.
