ANGLES AND SHAPES
BIG IDEAS:
(taken from “Big Ideas by Dr. Small”):
- Some attributes of shapes are quantitative, others are qualitative.
- Geometric shapes can be classified and sorted according to attributes.
- The measurement of an angle is defined by how much one arm turns around a vertex relative to the other arm.
