4.MD.6 Develop an understanding of angles and angle measurement.
- Understand angles as geometric shapes that are formed whenever two rays share a common endpoint, and are measured in degrees.
- Measure and sketch angles in whole-number degrees using a protractor.
- Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g. by using an equation with a symbol for the unknown angle measure.
Essential Concepts and Vocabulary:
- point, endpoint, ray, vertex, angle, types of angles (acute, obtuse, right, straight), fraction, circle, protractor, degrees, decompose, complementary angle, supplementary angle,
