I do “Math Movie Monday” most weeks with my high school classes, and we watched this video way back earlier in the year. My classes loved it! We paused the video at the right spot and took time to work independently. Then we acted it out. They begged for more, and I have done my best to throw some like this into the MMMs periodically. (I also do a similar search to your new favorite YouTube search, and we have looked at some of the riddles as well. As a side note, there’s also a lovely treatment of Hilbert’s Hotel.)

What’s especially great about this, though, is that after begging for more “bridge problems,” every time I find one that’s a twist, I get the inevitable “this is just like the …!” reaction, and my students have the confidence to begin to attack whatever new twist they encounter. And that confidence overflows into a million other little wonderful places. It’s been a fabulous find. I am definitely going to take your “what if” scenarios and add them to our mix. Thank you!

Hi Michael! We used this exact problem at the beginning of the year to establish a collaborative problem solving culture in our classroom! Video was engaging. I used edpuzzle to slow the video down for my students and had them take stock of all the important information as it went by.

Then my students presented their findings to the rest of the school at our community assembly and teachers came up to me afterwards asking for the link so they could do it on their own time.

Math FTW!
