Product Description
Protractor Practice: Extend Your Thinking - Crack the Code includes TWO fun activities, loaded with mental math and problem solving opportunities beyond the usual reading of the protractor starting with 0º. These puzzles include extensions for supplementary and complementary angles, as well as a separate angle search extension. Includes answer keys.

Please Note: These activities are designed to give students practice reading angles, not measuring them with real protractors. They need to use the protractor provided, and devise a way to extend the rays that do not touch that protractor. The problem solving has them adding and subtracting to find the measurements, using what they know about acute and obtuse angles.

Each Protractor Practice activity has several rays all starting in the same place, which muddies the point of origin, leading to inaccurate measurements, if students try to use a real protractor.
