Unit 1: Place Value and RoundingIn this unit students will:
● read numbers correctly through the millions
● write numbers correctly through millions in standard form
● write numbers correctly through millions in expanded form
● identify the place value name for multi-digit whole numbers
● identify the place value locations for multi-digit whole numbers
● round multi-digit whole numbers to any place
● solve multi-step problems using the four operations

2. How does understanding base-10 number system help us add and subtract?
3. How do digit values change as they are moved around in large numbers?
4. What determines the value of a digit?
5. How does estimation keep us from having to count large numbers individually?
6. How are large numbers estimated?
