### Use a Protractor

At this point of the year, students have learned to identify lines and angles. They should be able to define, describe, draw and identify examples of parallel, perpendicular, and intersecting lines. They should also be able to identify and draw examples of acute, right, and obtuse angles.

Next we will be measuring angles by using a protractor.

1. Dear class,
The person who invented protractors must be really useful himself, because without protractors, we would have a real bummer when it comes to drawing obtuse and acute angles. Protractors are like the Supermen of math because they are useful for drawing an important part of math, which we all know are called angles. What other things could protractors be useful for IN MATH? Well, they are not useful for combing your hair.
Sincerely, Fiona

2. Dear Mr. Pahl,
I think using the protractors is fun and useful because the people that are having trouble with angles can get a lot of help with the protractors to learn what an acute an obtuse and a right angle is.
Sincerely,
Shawn

3. Dear Mr. Pahl,
I think angles are fun. But with the protractor it’s even more fun!
Sincerely,
Ella
