Understand the place value system. 5.NBT: Understand the place value system. 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.
2.Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.
3.Read, write, and compare decimals to thousandths.
a.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) .
b.Compare two decimals to thousandths based on meanings of the digits in each place, using > , =, and < symbols to record the results of comparisons.
4.Use place value understanding to round decimals to any place.
