I’m a high school math teacher in the Chicago ‘burbs. I also coach the math team and am the class sponsor for the class of 2011. Once in a while I also do some consulting on math curriculum work.

I’m still trying to figure out how to best serve my students: to help them become students of mathematical thought. Every single student. I’m not there yet but I’m working on it. I’m also trying to figure out how to do this job well (and stay sane in the process).

I play with “Web 2.0” tools for my own learning and diversion. I’m still trying to figure out how/if/when to use them in the classroom.

You can contact me at jackie(dot)ballarini(at)gmail.com.  Or if you’re so inclined, I’m jackieb on Twitter.

    Jackie1618? I bet you thought I wouldn’t notice!

    Best of luck with the blog.

    1618 in no way reflects your use of the ratio. My ratio in your system would probably look too much like pi. I just needed a number and generally like phi.

    Oh no, I didn’t mean that. In fact, I was using 2718 already, and wanted a way to communicate the size of the issue without reference to grams or ounces or pounds or poods, so I ratioed my own irrational approximation. I picked 2718 because I like it (and because in high school other geeks already knew lots of digits of pi. So I picked a lesser chosen transcendental…)

    Help us promote math education with the Math Video Challenge!

    Dear Jackie,

    As a proponent of math education in the United States, we need your help to promote our nationwide math competition by blogging or posting about it on your blog/forum.

    As you probably already know, despite the fact that the US spends the most money on education per capita, our students are ranked 25th globally for math proficiency. The MATHCOUNTS Foundation is a nonprofit dedicated to improving that statistic. MATHCOUNTS’ third annual “ Math Video Challenge” is a math competition for 6th to 8th graders that encourages student innovation as they create and star in their own math videos, thus exciting them to pursue higher education in math.

    As the webmaster of Continuities, we are asking you to help support this effort by mentioning us in your next blog or forum post or promoting our logo with a link to the site. So far this contest has gathered over 500 submissions and millions of views on the videos. Our goal this year is this year is to do even better. With your help, we are confident we will reach this goal.

    For more information on MATHCOUNTS or the Math Video Challenge, visit our webpages at mathcounts.org and videochallenge.mathcounts.org/math-camera-action.
