Perform operations on multi-digit whole numbers and with decimals to thousandths.

5.NOS.B.4Fluently multiply multi-digit whole numbers. a. Apply estimation strategies to estimate products. b. Use computational strategies (e.g., partial products, doubling and halving) efficiently to multiply. c. Use a standard algorithm to multiply. d. Determine and explain when a strategy or algorithm is most efficient.5.NOS.B.5Divide multi-digit whole numbers with up to four-digit dividends and two-digit divisors. a. Apply estimation strategies to estimate quotients. b. Use partial quotients efficiently to divide. c. Use properties of operations and/or the inverse relationship between multiplication and division to divide. d. Represent and explain the computation by connecting rectangular arrays, area models, and/or equations to the meaning of division.5.NOS.B.6Apply and extend previous understanding of addition and subtraction of whole numbers to add and subtract decimals to hundredths. a. Apply estimation strategies to estimate sums and differences of decimals. b. Use concrete models, drawings, strategies based on place value (e.g., partial sums), properties of operations and/or the inverse relationship between addition and subtraction to add and subtract decimals. c. Use an algorithm to add and subtract decimals. d. Determine and explain when a strategy or algorithm is most efficient.5.NOS.B.7Apply and extend previous understanding of multiplication and division of whole numbers to multiply and divide decimals to hundredths in context. a. Apply estimation strategies to estimate products and quotients. b. Use concrete models, drawings, and arrays to multiply and divide. c. Use strategies based on place value (e.g., partial products, partial quotients) to multiply and divide. d.
