Final blog post for February.
I just uploaded another worksheet to the website, this one centering around writing/solving quadratic equations. The real world application is a bit exotic this time; students have to work out some of the logistics of owning a cruise liner. The inspiration came from a fairly common type of word problem, which involves finding the speed of a boat through water given a particular river current speed (as well as a few other pieces of information). Because the current affects the boat's speed relative to the shore differently when traveling upstream vs. downstream, the equation for time ends up being quadratic. For some reason, this worksheet took me a very long time to put together. I just had a hard time piecing together the different parts of the activity in my head, and I spent a lot of time sitting at the computer without making much progress. I am still not completely satisfied with it (in particular, I am not sure if the necessary "hints" I provided for the some of the problems are quite clear enough), but I am happy enough about it to post it on here. I think I will leave it for now and perhaps come back to it again later.
