We're trying to come up with the generalized process for solving equations. Now that we've got combining like terms and distribution and variables on both sides and sometimes no numbers, just a bunch of different letters and all the combinations of that stuff. What is it that we're really doing when we solve equations?
The supervising mentor that observes and works with our student teachers is a cool old guy, used to teach math, was a principle, still works in schools, and has no shame and no hesitation. He's smart and cheesy in the most compelling way and he fascinates and weirds out the kids when he comes. It's great. He's awesome. Last time he was here, I overheard him talking to a kid about how when we solve equations, we are trying to get x naked. That's why it makes sense to do inverse operations in the opposite order you use to evaluate, because when you're undressing you take off your shoes before your socks.
So I was trying to go with that, and here's what I came up with:
1- Who do you want to get naked? What do you want to solve for?
2- Focus their attention on you. Simplify the environment. Simplify the sides of the equation.
3- Get 'em in a room. Get all the variables (you're into) on one side of the equation.
4- Take off their clothes (shoes before socks, remember!) Use inverse operations to get variable alone.
5- Do they look good naked? Check your answer: does it make the equation true?
I almost told my kids this today, and ended up garbling it in an attempt to make it somewhat appropriate and talking about changing baby's diapers. I actually said "OK, wait, I'm thinking naked kids. No, I mean little kids," out loud. It was hilarious and memorable but pretty gauche.
I thought you guys might have some good ideas, either from experience or improving on this one. I want to laugh this much at school everyday.
