1. Remember my calculator post from last week? Well, some of my Finite Math students were still having a little bit of trouble using the calculator to do Regression on the calculator. This website on Cubic Regression seems to have done the trick for my students, and I don’t seem to be getting nearly as many questions about how to do regression on the calculator now have I have started to circulate this link around. So, I figured I would throw it out there as a resource for everyone else!
Sometimes I wonder how many people actually find this more annoying than useful.
I know, I know… I haven’t been posting a lot of statistics materials on here, but this is one actually turned out to be pretty sweet. Here’s how I did it: On the top dotplot each student plotted their month of birth, along with the month of birth for three other people such as their mother, father, sibling, or closest friend. Then on the bottom dotplot each student plotted the mean of each of the four numbers that they plotted on the top dotplot. It turns out that this beautifully illustrates the Central Limit Theorem. After I did this activity in class, I realized that this Central Limit Theorem Activity does the same thing except by having the students roll four dice and then subsequently finding the average of the four rolls. Ohhh well, a lesson learned.
I was researching the best way to use maps to introduce the topic of ordered pairs to a beginning algebra class, when I stumbled upon something totally different, and totally unique: A website called Wordle that takes text and turns it into JAVA created art. I actually threw the RSS feed for this website into their art generator (a wonderful option, by the way), and the results are below. Immediately, my wheels started spinning about how to use this in a math class, and viola! The nice people who write the Ed Tech 4 Math Blog Technology & Software For Teaching Math already have a nice post on how Math Vocabulary Becomes Art. As you can see from my attachments, Wordle can also provide word counts, which could lead to a lot of discussion about word frequencies, etc. Enjoy! This also means that a future post is still coming about using mapping in the classroom.
A few months ago I had students in my Basic College Math class create a game about fractions. One student created “Fraction Bingo”. I decided to search the web to see if there were printable bingo sheets available. Well, there were, along with some other activities that I found on the same website from Holt, Rinehart, and Winston. And below is a list of a few of my favorite ones, appropriate for college-level basic math classes (organized by topic):
- statistics on education in America
- statistics on OCC enrollment
- injuries in sports
- comparison of profits for Detroit Sports Teams
