Day 20: Volume and Surface Area (and Tin Men)

Today was mostly review on Surface Area and Volume. We did Deal or No Deal review again and I got much better investment from the students than last time. I was just going to do it for an hour but it ended up going another half an hour because the kids just wanted to continue.

After their test, we got started on the Tin Man Project. So far they’re really into it. I was so surprised by how many cardboard objects we got! I meant to take a picture of them all before the students got to them. I was worried since I was really the only one that had brought anything in until today. I didn’t think to send out an all-staff email to see if other teachers could bring in stuff but it turned out fine! Here’s some of their work so far and they will hopefully finish tomorrow:

Il y a encore beaucoup de travail à faire pour ce projet.

Day 19: Volume and Spheres

I love the surface area and volume unit and like Lisa Bejarano, I just wish there was more time for all the cool projects out there! I already had a couple that I knew I would do, but coming across Lisa’s blog post opened up so many more that all seem so awesome. It was hard to choose what to pick. But I decided on doing many 3 Act Tasks – the File Cabinet yesterday, and then today I did Dan Meyer’s You Pour, I Choose and Meatballs. I worked them in the same way that I did the File Cabinet yesterday, so they take a long time, but students are engaged, curious, and working the whole time. I had a bunch of other activities cued up from Lisa’s list but I will have to see if there is maybe time at the end of the semester during final review. I will be doing Elissa Miller’s Tin Man Surface Area Project next class now that we’ve talked about surface area of spheres. I’m very excited to see how that goes!

Funny asides:

  • Apparently when I said “sphere”, a good chunk of the class thought I said “spear”. So they were preparing themselves for “working with spears tomorrow”…
  • I got comments from the class about how I know a lot of guy math teachers that are in my videos. I showed two male teachers, and not my videos. But high schoolers can think what they want…
  • Before doing the Meatballs task, I told them about how I was a terrible cook and always run into problems when I try to cook a real meal. I said that the next video is something I still haven’t learned from and run into this problem too often. Had them guess what kind of problems I could run into making spaghetti and meatballs with marinara sauce. The guesses were hilarious and the cooking stories that came from it were even better.

J’aime que mes étudiants ont un sens de l’humour, même avec un cours d’été.
