Exploring Decimal Modeling with Base Ten Blocks

The video tutorial introduces the concept of modeling decimals using base 10 blocks. It begins by explaining the use of blocks to represent whole numbers, tenths, and hundredths. The instructor demonstrates how to model numbers like 2.32 and 3.05 using these blocks, drawing parallels to money. The tutorial also covers the use of a place value chart to understand decimal representation and provides practice exercises for students to reinforce their learning. The session emphasizes understanding the value of each block and how they combine to form decimal numbers.
