5.NBT.A.1.4. Ability to reason about the magnitude of whole numbers, decimals, and decimal fractions (Identify which digit is 10 times, 100 times, or 1/10, 1/100, etc. of another digit).

5.NBT.A.3a. Major Standard: Read, write, and compare decimals to thousandths (builds on grade 4 work to hundredths) â€“ Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g. 347.392 = 3x100+4x10+7x1+3x(1/10)+9x(1/100)+2x(1/1000).

5.NBT.A.3a.1. See the skills and knowledge that are stated in the standard.

5.NBT.A.3b. Major Standard: Read, write, and compare decimals to thousandths (builds on grade 4 work to hundredths) â€“ Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons (builds on work from 4.NBT.C.7 and 5.NBT.A.2).

5.NBT.B.7.1. Ability to use concrete models and pictorial representations to perform operations with decimals to hundredths.

5.NBT.B.7.2. Ability to recognize that the product is not always larger than its factors.
