3. Learning Goal
We will use our previous understanding of the parts of a (decimal) number so that we can properly compose and decompose decimal numbers. We’ll know we’ve got it when we are able to correctly recognize equivalent expressions.

5. Decomposing a Decimal Number
Decomposing a decimal number means to represent it using equivalent form. For example, the number can be decomposed in the following ways:
(3 x 1000) + (7 x 100) + (4 x 10) + (1 x 1) + (8 x 0.1) + (2 x 0.01) + (5 x 0.001)
(3 x 103) + (7 x 102) + (4 x 101) + (1 x 100) + (8 x 1/10) + (2 x 1/100) + (5 x 1/1000)

6. Equivalent Expressions
A place value chart is also a useful tool for identifying equivalent expressions
289 tenths = 28 units and 9 tenths = 28.9
673 hundredths = 6 units and 73 hundredths = 6.73
2361 thousandths = 2 units and 361 thousandths = 2.361
