In attempting to implement Thinking Classroom recommendations, I regularly run across ideas in twitter and (less often) in facebook. In order to find them again later, I will try to collect links here, in an updating list. At the start, at least, I will put newer entries on top. I doubt I will confirm any link stays alive beyond the time I paste here.

Big Wheel task (from Thinking Classrooms website)
You are standing in the living room of your ground floor apartment when a giant wheel rolls slowly past your window. The wheel is huge with a radius of 100 miles and when it passes the window it completely blocks out the light from outside. The question is, as the wheel begins to pass the window how will it appear to block out the light: (a) from the top of the window moving straight down, (b) from the side of the window moving straight across, or (c) from the top corner of the window moving diagonally down and across.
Video Game arbitrage (from Thinking Classrooms website)
I buy a video game for $10. I then sell it for $20. I buy it back for $30. Finally, I sell it again for $40. How much money did I make or lose?
Egg Timer task (from Thinking Classrooms website)
I have a 4-minute egg timer and a 7-minute egg timer—the kind that you turn over and let the sand run through. Can I use these to cook a 9-minute egg? If so, how long will someone have to wait for their egg?
