Angles Unlimited (Angles and Angle Pairs)

Students will use the internet to find pictures that show angles in everyday usage.  Students should report out, telling all they know about the angles they find.  Tier One students may be given a list of possible sites to investigate.  In their journals students will compare and contrast definitions and symbols.

Standards & Objectives

Learning objectives: 

Students will:

  • Move flexibly between multiple representations (contextual, physical written, verbal, iconic/pictorial, graphical, tabular, and symbolic), to solve problems
  • Develop the structures of geometry, such as lines, angles, planes, and planar figures, and explore their properties and relationships
  • Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement
  • Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure
Essential and guiding questions: 

Why is it important to have a good definition for angles and angle pairs?

What are the limits of geometrical representations and modeling?
