Here is a wonderful collection of 30 charming objects, each in three sizes, with three felt sorting mats, plus labels that are the same width as each mat. Children sort the objects and place them on the appropriate mats to practice size discrimination, then match labels to the mats to associate printed words with size terminology. Extensive Teaching Notes focus on key sorting and language concepts, and help with different ability levels. Includes storage basket and laminated word cards. Grades: PreK-1.
