Students apply place value knowledge and reasoning to read and write decimals to the thousandths by using standard, expanded, and word form. They compose and decompose the values of multi-digit numbers with decimals in multiple ways by using objects, drawings, and expressions or equations. Concrete models, place value charts, and number lines will support student understanding.

B.E.S.T. Benchmarks:

• MA.5.NSO.1.2 Read and write multidigit numbers with decimals to the thousandths using standard form, word form and expanded form.
• MA.5.NSO.1.3 Compose and decompose multidigit numbers with decimals to the thousandths in multiple ways using the values of the digits in each place. Demonstrate the compositions or decompositions using objects, drawings and expressions or equations.
