For our second instructional week, we will continue with PLACE VALUE and dig a little deeper!
The Big Idea: This week, we will focus on:
- 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
