Understanding Base Ten Concepts

Holly Russell, a second-grade teacher, explains the use of base ten blocks in the everyday math program. She describes the components of base ten blocks, including hundreds, tens, and ones, and introduces a shorthand method for representing these blocks. The video covers how to convert smaller blocks into larger ones and vice versa, which is useful for regrouping in addition and subtraction. The tutorial sets the stage for a future video on expand and trade subtraction.
