1. What questions perplex you about this photo?
Almost nothing went well here, which is what makes this particular moment so valuable for me. The image didn’t urge the question I thought it did, especially when I couldn’t easily clarify its meaning.
Sam Critchlow: how many players on a football team, are football babies bigger?
Chris: How many babies?
Matt: What do the yards and pounds represent?
Peter: what is 24,414 pounds? what is 7908 inches?
The intended question was:
Jazo: how many players?
I have no problem, in these situations, just asking the intended question, but I remind myself to tune my WCYDWT antenna to scan for a better provocation than this one.
2. What is your guess? What is a number you know is too high / too low?
Technical innovation: Google Forms to submit a) the guess and b) the upper / lower bound.
However you handle this, you’d rather not have one student’s developing number sense stunted by another student’s guess. Seriously. When I do this in class, everyone tracks within a standard deviation or two from the first guess, no matter how insane that first guess is. When JB says “the Eiffel Tower is 7 miles tall,” the next guess from AJ is “5 miles.”
3. How can you use math to tell if you’re right or not?
Peter: to know if your guess is right, divide total pounds by your guess
4. Play around. Decide if your guess was too high or too low.
We divided the total pounds (24,214) by one guess of 200 players.
Jazo: 121 pounds? sounds like a weak team
schwartz: less people!
