Get your students up out of their seats this Halloween!
I've done this activity for years, and it really satisfies all my students in a way that they can be learning, socializing, and moving around. I usually set a timer for how long they have to complete the activity to keep them from lingering too long at one question. You can also set limits for how many people can be at a certain question at one time if you think that will be a problem.
Hang the questions around the classroom or around the hallways for students to find.
