The Spindle Box ✨ The spindle box is a math lesson in the Early Childhood classroom that helps children develop a concrete understanding of numbers and quantity. Handling the spindles helps children physically feel and observe the difference between quantities. Beyond teaching quantity, this lesson also teaches number recognition and sequential order, as well as introducing the concept of zero. Montessori math is always tactile and hands on so children can build a concrete foundation for future
