3.NBT.3:
Number And Operations In Base Ten
Use Place Value Understanding And Properties Of Operations To Perform Multi-Digit Arithmetic.4
Multiply one-digit whole numbers by multiples of 10 in the range 10-90 (e.g., 9 x 80, 5 x 60) using strategies based on place value and properties of operations.
4.NBT.1:
Number And Operations In Base Ten
Generalize Place Value Understanding For Multi-Digit Whole Numbers.
Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 / 70 = 10 by applying concepts of place value and division.
4.NBT.5:
Number And Operations In Base Ten
Use Place Value Understanding And Properties Of Operations To Perform Multi-Digit Arithmetic.
Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
5.NBT.1:
Number And Operations In Base Ten
Understand The Place Value System.
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.5:
Number And Operations In Base Ten
Perform Operations With Multi-Digit Whole Numbers And With Decimals To Hundredths.
Fluently multiply multi-digit whole numbers using the standard algorithm.
5.NBT.2:
Number And Operations In Base Ten
Understand The Place Value System.
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.
