    For some reason I happened to see Jeopardy on 1/11/11 and I found the category ‘Body Count’ really intriguing.  When you read the clues, I think you’ll find it intriguing as well: 400 – Chambers of the heart squared 800 – Usual number of ribs divided by 8 1200 – Pairs of chromosomes times 2…

    Here is a list of helpful links that I compiled while teaching from “Calculus: Early Transcendental Functions,” 5th Ed. by Larson, Hostetler, and Edwards last summer.  These aren’t necessarily textbook specific, either.  Honestly, although it was just last summer, I was sort of still back in the dark ages and hadn’t yet made the jump into…

    Sometimes a search for the weirdest things will bring you some of the the most useful things, like this, a link from Panola College of dozens of Free Web-based tools that can be used to spice up an on-line class.  So, do you really want to know what I was searching for?  It was a Google Image…

    A student in one of my classes a few years ago did a project on The Number System.  This was the result.  It gave me a lot to think about in terms of just how to present Venn Diagrams. See the full gallery on Posterous
