Last night I wrote about non-examples. Today I saw one I haven’t seen before.
We were reviewing 2-D geometry from awhile ago. Two areas of focus in 8th grade plane geometry are the Pythagorean Theorem and applying angle rules to triangles, and we did a number of problems along those lines as a class (they especially like Mathy McMatherson’s parallel line mazes). Then students practiced on their own. Wrapped up class with a short exit ticket, including this question:
Most students nailed it. And I watched in horror as one student wrote on her paper, with complete confidence:
48 + 50 = 98
180 – 98 = 82
I’m thinking she’s not quite there.Definitely a case of blindly following what the teacher does. Not sure how best to circle back on this one.
