I switched up the lesson plan a bit, and we did 3 rounds of "zombie outbreaks" in my class, each with a different soundtrack. At this point in the semester, we've learned about linear, quadratic, and exponential functions. However, I don't tell my students which outbreak is which until we're done.

For each round, students meander around the room, and my "patient zero" student follows the rules for that round by infecting students in a certain way. (Infections are stickers on their hands). As we listen to the music, I announce every 15 seconds "End of day __, Wake up, everyone! It's the morning of day ___!" I make a big deal of everyone "freezing" at the end of the day to "sleep," and then we resume movement with waking up on the next day.

- Round 1: (Linear) Each day, the zombie "infects" 3 new people, but the new zombies cannot infect anyone.
- Round 2: (Quadratic) Each day, the zombie learns how to infect an additional 2 people per day (I tell them the zombie is learning to run faster each day, and so the first day is still 3 people, but then 5, 7, and so on). New zombies still cannot infect anyone.
- Round 3: (Exponential) Each day, every zombie is able to infect 1 person. New zombies have infection powers.

It's so funny to watch them play this - I always have a couple students that want to be infected, and a couple that don't, and run away from the zombie. The game usually turns into a mild game of tag/hide-and-seek.

Once infected, the students have to "report their infection to the CDC," which means dragging a picture of a person on the SMARTboard into a box for day 1, 2, 3, 4, 5, or 6. (whichever day they got infected).

Once the rounds are complete, we record our findings in our ISNs, and discuss what patterns we see. Usually my students identify round 1 and 3 almost immediately as linear and exponential. I also usually have 1-2 students that see the square number pattern as well, which leads us to label round 2 as quadratic.

We discuss the characteristics of each function that we remember (this is a great review right after spring break), and then write the equation for each round. Then we destroy the world. :)

They research in groups online to find the population of our school, city, county, state, country, continent, and the world. Then they solve for round 1 and 2 how many days it would take to infect that population. They use a guess and check method for exponentials, since Math 1 kids don't learn logs until next year.

Things I want to improve in the future:

- predictions about each round before we start (I want them to discuss which scenario will infect the most people in a week, in a year, etc.)
- "CDC Disaster Reports" as a lesson conclusion (I'd love each group to take 1 time period, maybe a week, 1 month, 6 months, 1 year, and write up the infection rate based on each scenario)

I LOVE this lesson idea! My students are currently obsessed with zombies, so this would be very fitting! Definitely adding this to my list of ideas to incorporate next year.

ReplyDeleteThis is great! Thanks for sharing :)

ReplyDeleteThis is totally hilarious. I have to do this!! I pinned it for later. Thanks for sharing.

ReplyDeleteOne way I've done this with my more spirited students is to do a modified "Heads-up 7-up" game. When the lights go off, it's night, their heads are down on the desks, and the zombies go about infecting people. When the lights go on, the new zombies stand up and we do our tally. The kids had a lot of fun, but it was easier to manage.

ReplyDeleteThis is a great mod! I can't wait to use it with my "more spirited" classes. Thank you.
