Illuminations: Post-Office Numbers

A post office is a good example of a real-world environment in which numbers of different types can be found.

Whole numbers and fractions are introduced. Numbers that occur in a greater variety of measurement situations can also be introduced. At this level, students should be encouraged to elaborate on the way numbers are used.
