Looking for Pythagoras

 

UNIT GOALS

In this unit, students explore the Pythagorean Theorem, square roots, and strategies for estimating square roots. In addition, irrational numbers are introduced.

The presentation of ideas in the unit reflects the historical development of the concept of irrational numbers. Early Greek mathematicians recognized the need for such numbers as they searched for a ratio of integers to represent the length of the sides of a square with certain areas, such as 2 square units.
