This is an entire year's collection of objectives including letters, numbers, colors, shapes, body parts, musical instruments, concepts and scientific concepts. It comes with a 2' x 3' poster as well as 208 interchangeable tiles. In our classroom we put the poster in a frame and used Velcro dots to affix each tile to the appropriate spot. They are easy to change out weekly or however you would like to space it. I can customize to your specific color and room theme. Just email me personally firstname.lastname@example.org.
