Division Using Base-Ten Blocks Representation (Part 1)

This video tutorial explains how to divide 432 by 12 using base-ten blocks and connects this concept to long division. It begins with an introduction to base-ten blocks, explaining the place values of cubes, flats, rods, and units. The number 432 is represented using these blocks, and the process of dividing it into 12 equal groups is demonstrated. The tutorial covers exchanging flats for rods and rods for units to facilitate division, ultimately showing that each group receives 36 units.
