Reflection: Checks for Understanding Pulling It All Together: Parallel Lines Unit Review - Section 1: Discussion of the Homework

 

The last problem in the homework provides expressions for the lengths_of_the_sides of a triangle. It clearly states that these expressions represent sides - yet a number of students in my class set the sum of these expressions equal to 180 degrees!  

Each year this is something that I see students do over and over again, and each time it takes me by surprise. When I question these students, trying to help them discover their mistake, it often takes a while for them to come to some sort of epiphany.

I have asked myself if there is some connection that I am failing to help my students make. Or is it good that the students grapple with this question? Maybe they'll remember their mistake more clearly in the future?  I don't know. This is something I'll need to watch for and I think I'll repeat this type of question from time to time.
