Phase:
After/Explain/Elaborate
Activity:
This learning activity is best used after a lesson on right, obtuse, and acute angles.
After watching the video, review the 3 types of angles from the video with the students. You can do this with an anchor chart or by writing their definitions on the board.
Right Angle - measures 90 degrees
Acute Angle - measures less than 90 degrees
Obtuse Angle - measures 91 - 179 degrees
Distribute the materials: (per student)
one black sheet of construction paper
one protractor
one silver sharpie or white paint pen
different colored pieces of construction paper cut into strips 1/2" wide x 3" long
glue
3 x 5 unlined index card (white)
pencil
Directions: Students will create angles by gluing 2 strips of colored construction paper to the black sheet of construction paper. Each type of angle should be represented by a different color. Example: pink - right, yellow - obtuse, blue - acute. Students should make a key for the color of angles associated with the type of angle on the white unlined index card and glue it on one of the corners of the black sheet for reference. When students have created their angles using the strips of colored construction paper, they will measure their angles with the protractor and record the measurement on the black sheet under each angle using the sharpie or paint pen.
Assessment Strategies:
Students will be assessed on the correct angle measurement of their angles as well as the type of angle they classify each angle.
Advanced Preparation:
The teacher will need a computer with internet connection and a projector to play the video. The teacher will also need to make an anchor chart for the angle definitions or write them on the dry erase board. The teacher will need to precut different colored pieces of construction paper cut into strips 1/2" wide x 3" long.
Variation Tips (optional):
Students may complete this learning activity individually, with a partner, or in a small group (3 students).
