Our new Whole Part Part tray designed to help visualize, and use manipulatives to help learn and understand breakig numbers into parts, both eaqual or unequal. Each set includes a tray, that is 11 inces in diameter and made from hard maple wood, as well as a set of tokens to place in the recessed circles to help set up the work. The set of tokens will include 2 of each number 1-10 and 1 of each number 11-20. While this style of learning is typically found in montessori style education, but crosses over well into most types of learning.
