Division Concepts with Base 10 Blocks

This video tutorial explains partition division using base 10 blocks. It demonstrates how to divide 91 by 7 by modeling 91 with rods and units, forming seven equal groups, and exchanging rods for units to ensure equal distribution. The process concludes with each group having 13, confirming that 91 divided by 7 equals 13.
