Young children construct mathematical thinking by exploring, manipulating, sorting and classifying concrete objects. Our PreK and Kindergarten classrooms are full of opportunities for children to interact with a wide variety of manipulatives and materials. These hands-on experiences are the building blocks upon which children approach basic math concepts such as one-to-one correspondence, counting, numbers, comparative size, capacity and quantity. Through these experiences our youngest students learn to see math in all environments and see themselves as math experts.
