## Reflection: Checks for Understanding Evaluating Expressions - Section 6: Ticket Out

The exit ticket was too tricky for some of the students.  I think it is important to promote thinking, but after 3 minutes of plugging away, I become concerned about their confidence themselves.  I never want the kids to leave the classroom feeling frustrated or defeated.

I encourage everyone to try something.  Then I cross off the beginning of this English phrase so it says, how many wheels are on w 18-wheelers? This helps everyone to meet the goal of writing something.

Flipping through the quick checks, I find that only one student got it right.  This question will be revisited tomorrow.
