This video tutorial explains how to regroup numbers using base 10 blocks. It covers the basics of base 10 blocks, including units, rods, and flats, and demonstrates two examples of regrouping numbers to use the least number of blocks. The first example involves regrouping 8 rods and 13 units, resulting in 9 rods and 3 units, which equals 93. The second example involves regrouping 3 flats, 9 rods, and 12 units, resulting in 4 flats and 2 units, which equals 402. The tutorial uses online base 10 blocks from the National Library of Virtual Manipulatives.
