Math Resources for Week of August 28 – September 1, 2017 (Place Value)

• Understand that the place value to the left of a digit represents 10 times that value, and the digit to right represents 1/10 of that digit.
• Compare and order whole numbers to the billions place
• Round numbers to the hundred thousands place
