How to Use This Tool

The Montessori Test Tube Division Method

This interactive tool simulates the Montessori "Test Tube Division" or "Racks and Tubes" material used to teach long division.

Steps in the Process:

1. Setup: Enter a dividend (number to be divided) and divisor (number to divide by)
2. Distribution: Starting from the left (highest place value), distribute beads into equal groups based on the divisor
3. Record: The number of complete groups becomes the first digit of the quotient
4. Remainders: Any remaining beads move to combine with the next place value
5. Continue: Repeat the process until all place values have been processed

Controls:

• Use "Next Step" and "Previous Step" to move through the division process
• Follow the instructions that appear below the division board
• Watch as the beads are distributed and quotient digits appear

This tool helps visualize the long division process by showing the concrete representation of what happens at each step.
