That is, if Maple is your thing. 2. How Much Does It Cost to Go to the SuperBowl and The History of the SuperBowl are potentially two useful Infographics for about this time of year that could provide for some discussion on Sports Statistics, etc. Although, I mainly just thought they were incredibly…

Today we discussed finding the Greatest Common Factor (GCF) and Least Common Multiple (LCM), another topic that students sometimes seem to have a problem with. I came up with the following problem, which sparked quite a lot of discussion in the classroom. But more than that, I think it is the type of problem that continues to reiterate the Order of Operations, and doesn't back…
