Mathematics in Context: Packages and Polygons

Dear Student,
Welcome to the unit Packages and Polygons.
Have you ever wondered why certain
items come in differently shaped
packages? The next time you are in a
grocery store, look at how things are
packaged. Why do you think table
salt comes in a cylindrical package?
Which packages do you think are the
most practical?
Geometric shapes are everywhere. Look at the skyline of a big city.
Can you see different shapes? Why do you think some buildings are
built using one shape and some using another?
In this unit, you will explore a variety of two- and three-dimensional
shapes and learn how they are related. You will build models of these
shapes using heavy paper, or straws and pipe cleaners, or gumdrops
and toothpicks. As you work through the unit, notice the shapes of
objects around you.
Think about how the ideas you are learning in class apply to those
shapes.
We hope you enjoy your investigations into packages and polygons.
Sincerely,
The Mathematics in Context Development Team
