Working With Angles

What's the Angle?
Math Make a matching set of cards, one set with the number of an angle, and the other set with pictures of the angle, ex., 45°, a picture of a 45° angle. Set the cards in a learning center where students can practice matching them on their own or play a kind of concentration game with a partner. For a quick spot-check, give a student a piece of yarn and ask him or her to show you an acute, right or obtuse angle, or even something close to a 45° angle.

Angles
Using this lesson students will be able to define right angles, obtuse angles and acute angles. They will also be able to draw right angles, obtuse angles and acute angles.

Measuring Angles
The student will analyze and measure angles using a protractor. They will also learn how to identify angles as right angle, acute angles, and obtuse angles.

Light and Angles
Students will predict, test, and explain what happens to light when it is reflected on a mirror through investigation of the path of the light at different angles.
