As a reward for doing so well and working so hard during the homeroom challenge, the entire 9th and 10th grades earned a party. Since 9B won, they got to choose what they wanted the party to be, and after deliberation (and lamenting about the irregularity of the weather during rainy season), it was decided that we would all go play laser tag together.
Initially, I was a little concerned how it would go over, but the kids really started getting into it, and those who were most successful were not necessarily the best athletes. Furthermore, we mixed all of the students into four different teams to help integration between classes and grades, promoting the overall unity of the school. It was a lot of fun and was truly a loss that they didn't allow cameras.
