Learning goals: Teacher Facing Comprehend and use the word “degrees” (in spoken and written language) and the symbol ∘ (in written language) to refer to the amount of turn between two different directions. Recognize $180^\circ$ and $360^\circ$ angles, and identify when adjacent angles add up to these amounts. Use reasoning about adjacent angles to determine the angle measures of pattern blocks, and justify (orally) the reasoning.
