Objectives
  • Students will identify angles as acute, obtuse or right.
  • Students will identify angles in everyday shapes and objects.
  • Students will use drawing or word processing software to draw the angles in the pictures
  • Students will contribute their favorite picture to a collaborative class book of "Angles All Around Us".
Procedure
  • Day 1
    1. Introduce geometry terms of acute, obtuse and right angles and their degree measurements.
    2. Have students record key terms in their math notebook.
    3. Draw angles on board, measuring with a teacher protractor.
      • Explain how we use degrees to measure angles.
      • Explain how important 90 degrees is in geometry.
    4. Have students stand and use their arms to demonstrate the measurement of 90 degrees.
      1. Students will also demonstrate what each angle; obtuse, right, and acute looks like with their arms.
    5. Teacher will show movie from IDEAL portal Discovery Streaming, The Assistant Professor: All about Angles, 17 minutes. May want to show only specific segments.
    6. Explain that math is all around us, even in this room. We can find it in the angles of various objects. Look at the bookshelf or the wall.
    7. Go outside and identify as many right, obtuse and acute angles as the class can find in the shapes of the objects around us.
    8. Divide students into small equal groups of 2-3, which will be dependent on how many digital cameras you have.
      1. Modification: If you do not have enough cameras for the class, this activity may be done with one camera. Students can identify the object with the angle and the teacher with one camera can choose who is going to take the picture and record the information.
      2. Explain the jobs of the each student.
        • Photographer-takes picture
        • Scout-officially "OK's" the angle for the picture
        • Recorder-records the angle and the location
      3. Teacher will go over how to handle/take pictures with cameras.
      4. Teacher takes classroom groups outside to allow students to explore the playground for acute, obtuse and right angles.
      5. Students will be given 20 minutes. At the end of 20 minutes, teacher notifies students to return to room.
  • Day 2:
    1. Students still working in teams will use computers/laptops and upload angle shapes photos to computer with cable or card reader.
    2. Student teams will open either a drawing software or Microsoft Word with drawing tools and import one picture at a time to a separate page. If possible, students can insert more than one picture to a page.
    3. Students will trace the obtuse, right or acute shape in the pictures that they saw on the playground.
    4. Students will use the text box tool to insert a text box then label each angle.
  • Independent Activity:
    • Student can play an interactive activity reinforcing right, obtuse and acute angles.
    • Hitting the Target
Materials
  • Computer
  • Speakers
  • Projector
  • Internet
  • Student laptops/computers
  • Teacher Protractor
  • Digital Cameras
  • Upload cables/Card Reader
  • Microsoft Word or a drawing software
  • Document camera
Assessment
  • Student knowledge will be assessed by the shared picture.
  • Student knowledge will be shared when they retell about the angles in the class book.
