This worksheet informs the teacher of the student’s prior knowledge of angles. Selection of angle B indicates a common misconception, that an angle with the same measure as another angle but with extended rays is bigger, even though the correct answer would be that both of the angles are the same.
On reflection of this question, multiple choice options would be appropriate:
A) Angle A is bigger.
B) Angle B is bigger.
C) Both are the same measure.
Standard addressed: MAFS.4.MD.3.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement
