Math 4 moms and dads

Nicole Lanford, newly in charge of covering Education for the News-Gazette, reports on an event tonight at Central. I would like to take you on a little journey that goes just a tad deeper. Slopes and parabolas are words, names we give to things.

For starters, using the famous formula mx+b, here is a plot of various slopes (m) with various values for x:

If you just want one line (*yawn*):

But it is more than just creating pretty pictures (and I love the pictures!). What is especially exciting about what Lindsay Polarek and LaDonna Fletcher are doing goes way beyond the words we use – it is the way they actually teach. I have spoken with both in the past, and I love their approach to teaching math concepts to students; they are throwing in the kitchen sink by allowing students to collaborate, deliberate and explore as they grapple with formulas, functions and visualizing. They make a point of relating new ideas to familiar ideas, to help make the “learning curve” a bit more manageable – ideas are connected, one to another. Students also work together on small projects. In effect, they are already doing “21st Century Education” in their practices.

 

Math 4 Moms and Dads is a way for parents to see how these teachers teach, or as the article says of Ms. Polarek, an “opportunity to connect with educators”:

“So many people have negative impressions of math, and we want to show that this doesn’t have to be the case,” she added. “We want parents to experience math the way their students are experiencing it — as opposed to how they may have experienced it when they were in school.” (quoted from Lanford’s article)

It is not so much about remembering how to find a slope given a pair of points or what the quadratic equation looks like. I believe it is more so parents can see and “experience” how their children are learning. And from what I gather, there is a lot more fun involved than when I was a kid. 🙂

 

The event is advertised for Central families (parents and students). But I would encourage you to talk with Ms. Polarek and Ms. Fletcher regardless.

 

Obligatory plug for Wolfram: while Wolfram’s products are not the only thing out there, I tend to like them because 1) they are local, and 2) their products are powerful and really cool. I am big on visualization, so I like being able to “see” what the numbers are trying to tell me.
