Measure, draw, and classify angles.

1:

Accurately measure angles.

4th

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.    Home Exploration

Challenge Problem:

In the attached worksheet, measure each angle and then classify them as being acute, obtuse, or right.

Target 2

:

1:

Identify angles as acute, obtuse, or right.

2:

Understand that angles have types based on their degree measures (acute, obtuse, and right).

4th

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.    Home Exploration
