5.NBT.A.1 - Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.
5.NBT.A.3 - Read, write, and compare decimals to thousandths.
Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 x 100 + 4 x 10 + 7 x 10 x 1 x 3 x (1/10) + 9 x (1/100) + 2 x (1/1000)
Compare two decimals to thousandths based on meanings of the digits in each place using <, =, and > symbols to record the results of comparisons.
5.NBT.A.4 - Use place value understanding to round decimals to any place.
5.NBT.B.7 - Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
