Description: This lesson uses the well-known Montessori material: the spindles and spindle boxes. The Direct Aims are: The spindles clarify the idea that the symbols represent a certain quantity of separate objects. To introduce the concept of zero and its symbol. To reinforce the natural sequence of the numerals. To show nine as the first group in our decimal system, not ten. The Indirect Aims are: Unconscious preparation for the decimal and metric systems. To move closer to abstraction due to the loose quantities (compared with the formed quantities of the rods). To reinforce the idea that there are no other symbols other than 0-9. 10 is a new level of number. Math starts with numeration from the numbers 1-10. Through hands-on didactic materials they build on the foundation of numerals to learn about the decimal system, numbers to 100, and the four operations.
