This document provides instructional content and strategies for teaching about angles. It defines different types of angles like acute, obtuse, and right angles using everyday referents. It lists tools like protractors and angle rulers that can measure angles. It also suggests instructional modifications to assist weaker students, like allowing multiple listens of audio explanations, and to challenge stronger students, such as taking photos of angles in real life.
1. Instructional Content and Strategies Organizer
Instructional Content
• A referent for a 45° angle is the angle created by a diagonal of a square and one of the sides of the square that share a common vertex.
• A referent for a 90° angle (right angle) is the angle created by the corner of a square.
• A referent for a 180° angle (straight angle) is the angle created by a straight line.
• Protractors and angle rulers are tools commonly used to measure angles.
• An acute angle has a measure between 0° and 90°.
• A right angle (square angle) has a measure of 90°.
• An obtuse angle has a measure between 90° and 180°.
• An acute triangle has three acute angles.
• A right triangle has one right angle and two acute angles.
• An obtuse triangle has one obtuse angle and two acute angles.

Major Instructional Strategies
Weakest Students Strongest Students
- Students are encouraged to take pictures or
• Students can listen to recorded audio (with TRX • Relating classroom information to real life. video recording of their real life angles
pictures) as many times as necessary. (homework assignment).
• Hands-on activities: measuring angles
• Students ask clarifying questions as necessary. around the classroom. - Students estimate actual measures of angles
instead of just greater than/less than referent
angles.
