I can explain how an angle represents a turn and how angles are measured in degrees.
Standard cap: 4 - Apply angle-turn reasoning to a new situation.
Subskills what students must be able to do
- 1I can explain how two rays form an angle.
- 2I can connect angle size to a turn around a circle.
- 3I can explain that degrees measure the size of the turn.

“Show the vertex and two rays that make this angle.”
“Which represents a larger turn: 1/4 turn or 1/2 turn?”
“Explain why a full turn is 360° and how degrees describe angle size.”
“A robot must make a total turn of 225° using only 90° and 45° turns. Find two different sequences of turns that work and explain why both represent the same total turn.”
