Wow! What a lesson. Students were challenged to consider prior knowlege, and to really question their understanding of angles.
We planned a great lesson, and realized, as we presented the lesson, that students were confusing ‘interior angle sums’ with area and perimeter.
We realized that students need to be challenged to figure out what the problem is asking and how to get t the answer.
