Rounding

Understand how our number system works and how quantities are represented.

WHY LEARN THIS?

This idea has a purpose.

Mathematics becomes much easier when you understand what a tool was designed to accomplish. This lesson will build Rounding from the idea itself instead of asking you to memorize a rule first.

Places this kind of mathematics can appear:

counting inventory
reading addresses
estimating crowds
understanding large quantities
