## Reflection: Student Self-Assessment Gallery Walk of Application Problems Involving Radicals - Section 3: Gallery Walk

Today, my students seemed to be more confident with simplifying radicals.  Poster 1 was difficult for some students to complete because of time.  Poster 5 was a struggle for most groups despite the review undertaken in the Warm Up for the lesson.

After observing this lesson, I know that some of my students need to see multiplication or squaring repeated.  Multiplying radicals is covered in the next lesson so that should help students with Poster 5. The first step in Poster 6, was easy for most students to evaluate the distance from the heights of both buildings.  However, some of the students forgot the second step, to find the difference between their two answers.

I changed this lesson the second time I presented it.  For the Gallery Walk, I had students solve the application problem on the first poster they were assigned for 10 minutes, and then move to each poster in numerical order.  After the solving the problem on the first poster, students were to provide feedback on the other posters with sticky notes.  Students were to either to write a feedback statement or question at each poster.  Finally, students were to return to their poster, and synthesize the feedback statements and questions.  After reviewing the feedback to improve their solution, they were to use their own judgement on how to present the problem to the class.
