Thursday and Friday, September 12th and 13th - Investigation 1.3

Today we launched and explored Investigation 1.3 - Estimating Measures of Rotations and Angles.  

Here is the Focus Question for today:

Students learned that two rays with common endpoint form two rotation angles.  One of them being the initial side and the other being the terminal.  Reviewing back to the previous lesson the angles measure from the initial side counterclockwise to the terminal side.

Students needed to complete Problem 1.3 on pages 16-17 and then ACE Problems #10-18.
