This product is perfect for a file folder in centers or using in teaching small group/individual lessons on the size concepts of big and small.Great for preschool or special education and can be used for sorting, labeling, and identifying. Images for this document were provided by Tobii Dynavox and Boardmaker. I use Boardmaker’s PCS symbol library for our products because I love the clear, easy-to-understand look of the pictures. Plus, this provides an amazing consistency across our products.
