Standards
5.NBT.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 × 100 + 4 ×
10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (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.
