Teaching Guide Unit 1

Pacing 4 weeks plus 1 week for reinforcing/enriching

All unit standards are interrelated. Standards should not be taught in isolation.

• 5.NBT.1. Recognize that in a multi-digit number, a digit in the ones 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.2. Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, an explain patterns in the placement of the decimal point exponents to denote powers of 10.

• 5.NBT.3. Read, write, and compare decimals to thousandths.

  • 5. NBT. 3. a. Read and write decimals to thousandths using base-ten numerals, number names, and expanded from, e.g., 347.392=3x100+4x10+7x1+3x (1/10) +9x (1/100) +2x (1/1000).

  • 5. NBT. 3. b. Compare two decimals to thousandths based on the meanings of the digits in each place, using, =, and <symbols to record the results of the comparisons.

• 5.NBT.4. Use place value understanding to round decimals to any place.

Students Outcomes:

powers of ten.

• Explain patterns in numbers when multiplying and dividing by powers of ten as it relates to the number of zeros in a number or the placement of a decimal point.

• Read, write, and compare decimals to thousandths using base-ten numerals, number names, and expanded form.

• Round decimals to any place using place value.

• Explain how the value of a digit is 10 times as much as the digit to the right or 1/10 less to the left.
