Protractor Fun

Students are learning how to use a protractor to measure angles.  This can be a very tricky tool to use as it's important to place it on the angle you are measuring properly in order to get an accurate measurement.  Also, angles can be measured from the right or the left, hence a protractor has two sets of numbers.  We have to be very aware of which numbers to use, therefore applying our math thinking and knowledge of kinds of angles.

We are using protractors to both draw and measure angles.  Once we've gotten it, it doesn't seem so tricky anymore. :)  Thankfully Singapore Math has some wonderful online resources for us to use in the classroom.
