Students learn how to write ordinary numbers in standard form using place value.

Later, as learning progresses they convert numbers in standard form back to ordinary form.

**Differentiated Learning Objectives**

- All students should be able to convert numbers greater than one to and from standard form.
- Most students should be able to convert numbers greater or less than one to and from standard form.
- Some students should be able to perform calculations using the rules of indices with numbers written in standard form.
