Title:

Wanted: Angles of all Sizes!

Overview/Annotation:

In this lesson, students will explore straight, right, acute and obtuse angles. Students will go to the playground to search for angles. The students will use digital cameras to record their findings. They will use their findings to create a PowerPoint to present to the class.

27. Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines, and identify these in two-dimensional figures.
Unpacked Content
Evidence Of Student Attainment:
Students:
  • Describe the characteristics of a given figure.
    Example: An obtuse angle is described as two rays that meet at a point called a vertex with an angle measure greater than 90 degrees.
  • Draw a given figure correctly using a variety of tools.

  • Example: Use a ruler, paper, and pencil to draw two points and connect them to create a line segment.
  • Identify the given figures in two-dimensional shapes.

  • Example: Given a rectangle ABCD, identify that angle ABC is a right angle and that lines AB and CD are parallel.

  • Point
  • Line
  • Line segment
  • Ray
  • Right angle
  • Acute angle
  • Obtuse angle
  • Perpendicular lines
  • Parallel lines
  • Two dimensional figure
  • Vertex
  • Angle measure

Primary Learning Objective(s):

Students will be able to work collaboratively to identify straight, right, obtuse, and acute angles. 

Additional Learning Objective(s):

 
 Preparation Information 

Total Duration:

Greater than 120 Minutes

Materials and Resources:

Per Group: My Angles Drawings Handout, Pencils

Technology Resources Needed:

Per Group: digital camera, computer (with PowerPoint software), Interactive Board or Projector, flash drive

Background/Preparation:

Teacher prep: Students need to be put into cooperative groups of four before starting this activity. The teacher should have a digital camera and an angles worksheet available for each group.

Student prep: Students should have basic knowledge of the definition of a straight, right, acute, and obtuse angle. Students should have prior knowledge of creating a PowerPoint using a digital camera. Students should also be aware of the rules of working in collaborative groups.

  Procedures/Activities: 

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

Allow each group to present/communicate their findings to the class.


  Assessment  

Assessment Strategies

Students will be assessed on their presentation to the class. They will be assessed on whether they correctly captured and identified the four types of angles.
