Making Error Analysis Work

Happy planning period! I am in need of some help in reflecting on yesterday's assignment and why/how it went wrong. The kids didn't have the reaction to them that I desired, and I want to correct it for next time, because I truly feel the activity is a valuable one.

Using Steph Reilly's Error Analysis format, I came up with, what I thought, was a great activity for my geometry classes to reflect on the major errors they commit when solving equations. I should frame this by saying that I gave an exit ticket last week and saw that my kids were still severely struggling with solving equations, so they truly did have lots of things to learn by doing the Error Analysis activity.

Here is the sheet of exit ticket errors and reflection space I made:

And here are they type of reflections I got from about a third of my first period class:

Now, some kids seemed to find it helpful, and the quiz scores today reflect that. However, the activity yesterday really confused a few kids, and it was also reflected in their quiz scores today.

How do I restructure this activity so it's beneficial for everyone next time?
