Angles Everywhere!

Art?  Check.

Architecture?  Check.

Movement?  Check. 

We broke out the protractors again to work toward proficiency in constructing (drawing) and measuring angles.

Fourth grade Math students should be able to construct angles 180 degrees or less and measure angles less than 360 degrees with a protractor (using both the outer and inner scales).  Remember, it's helpful to use benchmark angles (90, 180, 45, 30 degrees) to decompose and measure angles greater than 180 degrees.  :-)


Not sure about the whole protractor thing?

As usual, Khan Academy has some awesome tutorial videos, too!  Scroll down the menu on the left side of the screen when you open the link.

A quiz will be given on this benchmark on Thursday, April 28.
