The teacher needs to understand the role place value has in understanding whole numbers.  Understanding place value and the base ten number system helps students apply the same rules to decimals in later grades.

Student Knowledge Goals

I know whole numbers from zero to one million.
I know the names and values of the digits in any given place value position up to one million.
I know the rules for rounding to any selected place value up to one million, beyond just the leading digit.
I can determine whether the digit being rounded goes up by one or stays the same based on the value of the digit to the right.
I can use place value models to reason about numbers.
