## Reflection: Checks for Understanding The Pythagorean Identities - Section 1: Bell Work

When students are working on a problem I move around the room checking students work. Some issues students have is not wanting to use any notes when they are working. Students are good about taking notes but they seem to think using the notes during the learning process is not correct.

To help students learn how to use reference sheets and notes, I will ask a student who is struggling to see any notes they have on the topic. It sometimes takes students time to get those notes out but I will than start looking over the notes and "think out loud"  by saying "I wonder if there is something we did yesterday that may help me with this problem." This jogs some students memory and they look at the example and finish the problem.

Other students will not have notes or reference sheets. I will ask others in their group if they have some notes that can be borrowed.

Some students will be completely confused. These students will need more individual work and I will have to work with them individually.  I will bring the students back to plotting the point in the coordinate plane and labeling the sides of a triangle. For some students this is the easiest way to find the other trigonometric values.  I will work with these students when we have practice time or after school in tutoring.
