Contents

  1. 1 Understand the place value system (NBT.1 - NBT.4)
    1. 1.1 NBT.1 - Recognize that each place value is 10x greater than the place value to the right and 1/10 as large as the place value to the left. 
    2. 1.2 NBT.2 - Explain patterns of zeros in a number, including explaining decimal placement, when multiplying or dividing by a power of 10 & show powers of 10 by using exponents.  
    3. 1.3 NBT.3 - Read, write, and compare decimals to thousandths.
    4. 1.4 NBT.4 - Use place value understanding to round decimals to any place.
  2. 2 Perform operations with multi-digit whole numbers and with decimals to hundredths (NBT.5 - NBT.7)
    1. 2.1 NBT.5 - Fluently multiply multi-digit whole numbers using the standard algorithm.
    2. 2.2 NBT.6 - Divide up to four-digit dividends by two-digit divisors, illustrate and explain it by using equations, arrays and models. 
    3. 2.3 NBT.7 - Add, subtract, multiply, and divide decimals to hundredths, and use concrete models, drawings and other strategies to explain method used.


Understand the place value system (NBT.1 - NBT.4)

NBT.1 - Recognize that each place value is 10x greater than the place value to the right and 1/10 as large as the place value to the left. 


NBT.2 - Explain patterns of zeros in a number, including explaining decimal placement, when multiplying or dividing by a power of 10 & show powers of 10 by using exponents.  


NBT.3 - Read, write, and compare decimals to thousandths.

3a - Read and write decimals to thousandths using base-ten numerals, number names, and expanded form [347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000)].


3b. Compare two decimals to thousandths.


NBT.4 - Use place value understanding to round decimals to any place.



Perform operations with multi-digit whole numbers and with decimals to hundredths (NBT.5 - NBT.7)

NBT.5 - Fluently multiply multi-digit whole numbers using the standard algorithm.


NBT.6 - Divide up to four-digit dividends by two-digit divisors, illustrate and explain it by using equations, arrays and models. 


NBT.7 - Add, subtract, multiply, and divide decimals to hundredths, and use concrete models, drawings and other strategies to explain method used.
