Homework Gallery Walk

You may have done a gallery walk to share projects before.  But what about using a gallery walk to grade homework?

For Homework Gallery Walk, place numbered paper, one for each assignment item, around the room.  All students take their assignment and start at an item.  They write the answer they had for that problem, then rotate to the next item and repeat. Students should initial their contribution each rotation so you can later look through their thought process.


If their answer is different than what's already been written, they consider if they are right or made a mistake.  If they feel they are right, they contribute their answer.  If they feel they were wrong, they write an explanation on the Gallery Walk paper of what they originally did wrong and correct that problem on their paper.  


Rotations continue, and once correct answers are established, students dig deeper into their thinking.  Here are some suggested metacognitive questions.

  • What is your answer?

  • How do you know your answer is correct?

  • How do you know your answer is incorrect?

  • Show your work/page number/proof.

  • What was your error?

  • What is a strategy you used?

  • What is a resource you used?

  • What could you type into Google to find help for this problem?

  • What do you wish you had asked/understood yesterday to be able to do this problem?

  • What is an example that would have helped you with this problem?

  • What vocabulary terms/skills are important to this problem?

  • What did you find easy about the problem?

  • What did you find difficult about the problem?

  • How did your thinking about the problem change?

  • What other homework item is this problem similar to?

  • How are they similar?

  • If you gave this problem a title, what would it be?

  • How does this problem relate to something else you’ve learned?

  • What questions about this content do you still have?

  • What skills might someone need to already know to be able to do this problem?

  • What was a common error with this problem?

  • What tip would you give someone who was just learning this content?

  • How could you change this problem to make it easier/harder/deeper?

  • Why might you need this skill/knowledge outside of school?

Homework Gallery Walk holds students accountable to doing the assignment so they have something worthwhile to contribute, but even if they (gasp!) didn't do the assignment, participating in this process will expose them to the thinking of their classmates AND guide them to think on their own so they have something to write.  Students will think deeply about the content and build connections between concepts so they understand far more than just a correct answer.  And you know how deeply your students are really understanding your content far more than a 7/10 would say.

Homework Gallery Walk can even be done in complete silence to force students to explain themselves and argue their thinking only in writing.

You can download your own copy of the Gallery Walk handout here.

For shorter assignments, supporting struggling students, or real-time collaboration, students can rotate through in small groups.

This process can also be used to answer questions in class, respond to prompts, go over a test, argue and debate, etc.  Try pairing it with Musical Desks!
