Final answer:
The teacher gives students self-stick notes in the reflection stage of gallery walks to write comments about each student's work.
Step-by-step explanation:
The teacher gives students small self-stick notes on which to write comments about each student's work in Option 4: The reflection stage of gallery walks.
In the reflection stage, students are given the opportunity to provide feedback and comments on each other's work. This allows for a thoughtful and constructive evaluation of the artwork. The self-stick notes serve as a way for students to write down their observations, insights, and suggestions for improvement.
During this stage, students can write comments such as praising the use of color or technique, pointing out areas that could be improved, or asking questions to deepen their understanding of the artwork.
