Dear Student,
Did you ever want to know the height of a tree that you could
not climb? Do you ever wonder how people estimate the width
of a river?
Have you ever investigated designs
made with triangles?
In this Mathematics in Context unit,
It’s All The Same, you will explore
geometric designs called tessellations. You will arrange triangles
in different patterns, and you will measure lengths and compare
angles in your patterns. You will also explore similar triangles and
use them to find distances that you cannot measure directly.
As you work through the problems in this unit, look for tessellations
in your home and in your school. Look for situations where you can
use tessellations and similar triangles to find lengths, heights, or
other distances. Describe these situations in a notebook and share
them with your class. Have fun exploring triangles, similarity, and
tessellations!
Sincerely,
The Mathematics in Context Development Team
