Engage the students by asking them to look around the classroom and identify four angles. The students will discuss their angles with their tables. Students should discuss if the angles are larger or smaller than 90 degrees. Call the class together and allow each table to share their favorite findings. If the students are not accurately describing straight, right, acute, and obtuse angles, then reteach the definitions of each and give visual examples throughout the room. This engagement should only last 10-15 minutes.
Students will explore and identify more straight, acute, obtuse, and right angles by going outside to search for these angles on the playground. They will use the My Angles Drawing Handout to record their findings. Students will use digital cameras to take pictures of where they locate each angle. Students must identify and take a picture of each type of angle. Allow 15-20 minutes for this exploration.
Bring the class back together. Each cooperative group of students will use their recordings on the digital cameras to create a Power Point. On the PowerPoint, each group must identify the type of angle on each picture. They must also explain how they know that it is right, straight, acute, or obtuse angle. This part of the lesson will be done in the computer lab. Students are encouraged to be creative as they create their PowerPoint. Students are to save their work to a flash drive. Allow 60-75 minutes for this part of the lesson.
Allow each group to present/communicate their findings to the class.
