Big Ideas: Numbers can be decomposed into parts. This lesson builds on understandings developed in fourth grade of reading, writing, and comparing decimals using numbers, words, and expanded notation. This task focuses on writing decimal numbers to the thousandths in expanded form by using base ten blocks. This lesson builds towards future work in fifth grade when students will reason about differences in the values of like place value units and express those comparisons with symbols (>, <, and =).
