###### Vocabulary:

Angles, Degrees, Protractors

Activities:

- Learned that a protractor is a tool used to measure angles.
- Learned the main features, i.e. the "bullseye," baseline, and numbers/degrees 0-180, of a protractor and how to use them to accurately measure angles.
- Given a specific angle measure (angle measures having multiples of 5 degrees), students used protractors to draw angles.
- Practiced new notations for angles and degrees as units.

###### Vocabulary:

Acute, Obtuse, Right Angles

Activities:

- Found real world examples of right angles around the class and know that the measure is always 90 degrees.
- Learned that angles can be classified into groups--acute, obtuse, and right.
- Identified the parameters for the measure of acute and obtuse angles; acute angles are <90 degrees but >0 degrees while obtuse angles are >90 degrees and <180 degrees.
- `Drew angles using a protractor and classified them.
