Summer Camp has concluded. It exceeded expectations. In the end I had 40 campers who learned a lot of stuff and played a lot of games. And for a brief second we were almost derailed by a tropical storm, but a Tuesday night right turn sent it elsewhere. Let me take an opportunity to break down the lessons in greater detail and give you a glimpse of the economics of running this thing.
What's it cost to run this thing? I charge a $20 fee (there were 4 no-shows), got a donation to cover food expenses, and my principal is able to compensate me (we have a policy where certain extra duties can earn you $25/hr assuming that duty is approved as extra).
Overall I wound up behind by like $30. Primarily due to some drones that broke between Session 1 and 2. Fees get deposited into an activity account I control and expenses can be deducted from there. It's the same account that covers operating Varsity Math as a whole. Anyone who has been the business long enough knows most of this gain will roll back into classroom supplies at some point.
Some general information on who attends:
The kids attending got some basics during the school year. The spreadsheet lesson expands on that with a study of conditionals (if statements and conditional formats), specifying ranges, using built-in formulas, sorting, and how to lock on specific cells. After some brief explanation, kids spend 25 minutes figuring some things out with a dummy data sheet (~50 entries of names, ages, locations, and preferences). Functions used: COUNT, AVERAGE, MEDIAN, MIN, MAX, COUNTIF, IF, SUMIF, SUM, and RANDBETWEEN.
A discussion of the physics behind drones, and examples of what various amounts of money get you (from $25 to $1200). The main takeaways are that all quad copters operate on the same control scheme, operate with localized 3D coordinate systems, and more money gets you a greater set of self-preservation features. Kids spend 15-20 minutes flying a drone from a set of 6.
Once the batteries die we go back in the classroom and I give them an opportunity to fly a Mavic Pro if they're feeling brave. Fun fact, they all find it easier to fly than the smaller ones. The extra money buys you a lot nicer flight platform.
Let's Buy a House and Car
A short version of the lesson Calculus students got at the end of last year. We build a spreadsheet that calculates monthly payments for a house and car based on loan terms and amount borrowed. It then adds the payments together and outputs the theoretical yearly income to afford that stuff. Students pair up and role play as if they were making the purchasing decision together. One student finds a house (max $300,000), the other finds a car (max $35,000). Once they agree they come visit the bank and ask for a loan (randomized on index cards handed out by me). They make use of the local real estate database and property tax database to get a real sense of what it's like to own a home. Then for fun we see what it'd be like to manage a house that costs a few million. "I don't want to grow up" is the common sentiment at the end of this one. Primary goal of this lesson is to debunk the myth that renting is for suckers (given our location in a big city, most of our students rent).
A quick intro lesson involving variance and standard deviation. We start with giant bags of peanut M&Ms. Kids get a partner, bag of M&Ms, and open a shared spreadsheet to input the counts of the colors in their bag and the total candies in their bag. We have a discussion on what seems "normal" for a particular color and which bags are outliers.
I walk them through calculating the variances and standard deviation of the bag totals, then have them analyze the individual colors. We talk about what we can infer from the standard deviation, with the caveat that we'd need a bigger sample to apply this logic to all M&Ms.
Then I have them collect wingspans and heights in centimeters.
They perform the same analysis. We talk about who represents the average person in the room and whether the bigger sample size makes this more statistically significant.
I started my career in construction, managing budgets, writing contracts, and dealing with the million little problems that result when trying to put a building together. I hung onto the drawings from one of the projects I worked on. I pick one little area and pass out most of the drawings associated with that section (wall layout, electrical, fire protection, etc).
They spend some time with a partner deciding which drawing is which (they aren't labeled). I let them wander in the wilderness for a bit and then provide some vocabulary to help. Once we're in a agreement we talk about some of the finer details on each drawing and I show them the larger drawing that these were sourced from.
After some Q&A of what it's like to be 23 with a staff and 4 and in charge of $7 million, they get an engineering task of their own. It's your standard pasta structure that supports a tennis ball, but pasta costs money ($1 for round spaghetti, $2 for flat linguine) and so does tape ($2/ft for painter's tape, $5/ft for duct tape, $10/ft for electrical tape). Assuming the structure succeeds at the task, we discuss the various amounts groups were able to spend and accomplish the task.
Students don't get enough exposure to games. I spent the last year finding a variety of things to teach them. Some of them became huge fan favorites. Coup was by far the surprise hit. Once introduced they'd often get a game going as we waited for everyone to show up in the morning.
- Spit on (or Screw) Your Neighbor - a quick card game my relatives taught me
- Coup - an advanced rock/paper/scissors kind of situations where bluffing plays a big role
- Trivia Murder Party - part of the Jackbox Party Pack (sold on consoles, I used a Nintendo Switch), 8 players and an audience compete in a trivia game with a twist, it has a fantastic final round mechanic
- Z-Ward - a parsely game from Memento Mori, an RPG-lite experience modeled off text adventures from the 80s where kids take turns giving one command at a time
- Flappy Space Program - get as many little birdies orbiting your planet as possible
- Wits and Wagers - if Estimation 180 were made into a board game
- 5 x 5 - the excellent quick strategy game from Sara VanDerWerf
