Earlier this semester (before I got sick for an extended period of two and a half weeks), I was really entergetic about trying out new ideas in the classroom. Although the execution by the students could have been a little better, the students were engaged, which counts as a big deal to me. If I do this haunted house activity with students in the future, there are a few things that I know that I would do differently, such as having a precise rubric prepared to hand out to the students that checks for participation (some students particpated less than others within the same group), understanding of the mathematics (some groups did not use as much math in their project as others), and overall quality. A few pictures from the frightful day are posted below. Enjoy!
