Classifying Angles

Published on 10/16/2005

Activity Overview

Students will create a variety of angles using the Geoboard APP. The teacher will use Screen Capture to display the angles created by the students and will lead a discussion on whether the angles are acute, right, or obtuse.

Before the Activity

Students will log in to NavNet and exit the APP.

During the Activity

Students will select the GEOBOARD APP. Tell them to choose a square, 6x6 board. Each student will create an angle. Use Screen Capture to collect and display the angles. Ask the students to help you sort the angles into categories of less than 90 degrees, 90 degrees (if appropriate), and more than 90 degrees. Prompt students to create examples of all three types of triangles and discuss their work.

After the Activity

Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
