My Favourite Problem

Hands down, the following is my favourite problem from this school year.

I put this up on the IWB for my grade 9 applied classes, and after a brief discussion they had their problem:

When will he be able to use his iPod again?

Assume the picture was just taken (10:45 am, January 5, 2016). Off they went to work on the vertical non-permanent surfaces (VNPS) HT @alexoverwijk in their visibly random groups (VRGs) via Superteachertools HT @fawnpnguyen.

Plenty of great discussion and learning about units of time, and rates. We ended up with a few different solutions, but were any of them correct?

To be honest, I doesn't matter if anyone was correct, it was just really fun to see the vast majority actively engaged in problem solving. Bonus learning: Days in each month, days in a year, weeks in a year, "what's a leap year?" and what to do if this ever happens to you.
