Probability Illustrated

Currently, I’m working on a rapid e-Learning solution for teaching probability. I was able to quickly use PowerPoint and some clipart to put both the storyboard and the template for the interactivity. I use the animation features in both PowerPoint and Captivate to create the effects and interactive features for the piece. I’d like to spend more time explaining my process for this, but I will save that for a future post.

I created two presentations:

  • Probability and Dependent Events
  • Probability and Independent Events

Actually, the text of both of the presentations comes almost directly from text written by the Subject Matter Expert who intended to have it read online as one would read a print document. Somehow, it didn’t seem engaging enough to me so I went about creating these visual multimedia presentations. Unfortunately I can’t share the finished product up here, but I can share the images of the storyboards.  Both presentations are included in the gallery below.

Using Podcasts to Teach Math

I was just trying to think of at least 10 ways to use podcasts to teach math. Can you think of any others. Please post your ideas to this post in the comments. Please note, timeliness is not an issue. I’ll be checking this post in the future.

10 ways to use podcasts (vodcasts) to teach Math?

  1. Post a monthly puzzler or a brain teaser as an audio recording. Students have to listen carefully to the words and vocabulary used to figure it out.
  2. Students share their own math stories and problems.
  3. Broadcast monthly updates to both parents and teachers on the types of math lessons and activities students will be focusing on.
  4. Create a podcast with your students on math related subjects. Your students act as researchers and reporters who broadcast the stories.
  5. Share any news or media stories related to math.
  6. Broadcast homework and major assignment reminders.
  7. For those who do not have video or multimedia capability. Create math puzzles, problems, and diagrams in PowerPoint then provide audio narration to go with it in the podcast.
  8. Find, listen to and share math podcasts that you find.
  9. Students create their own math riddles and share them.
  10. On a professional level, share your experiences teaching math with other teachers.

Additional notes:

I found two interesting sites with math related podcasts/vodcasts:

The Math Factor (brief math converation and puzzle):

Math Train TV (math vodcasts created by middle school students):

I love Probability with Ben & Jerry!

These students did a fairly good job demonstrating Probability. Click the image below to view the video:


It still irks me… when women belittle their math skills

Warning: I’m on the soapbox kick. Sorry lately I’ve been in a mood of sorts.

It still bothers me that there are people out there who really thought that being a girl makes you less adept at math. I think I ran into (or had the oppportunity to listen to) at least three women, all above the age of 50, last month who expressed their own shortcomings in math. They all seemed resigned to the fact that they were terrible at math and that they could never be good at it.


I have two words for those women who still think that women of past generations weren’t  or couldn’t be stacked in the Mathematics department: Hedy Lamarr. Lamarr was not just a pretty face. She was a gifted inventor and engineer developed the idea for technology which has influenced the development of cell-phone and wireless tech.  “Any girl can be glamorous,” Hedy Lamarr once said. “All she has to do is stand still and look stupid.” She must have had brains and guts to cope with living in her times. I wasn’t able to find much about her formal education in mathematics or engineering, other than hints that she learned a great deal from work with one of her husbands, who developed guidance technology for weapons.

And about womens’ so called deficiencies in Math…. sure the circuits in your brain may not be as fresh as daisies*, but anyone can learn how to master functional mathematics. Most adults unless they have a severely debilitating brain disorder can figure out how to balance their checkbook. I’m sure most of those ladies who made these comments about their lack of Math skills understood how to do this and quite well. At least two of them are fairly good knitters so they unwittingly or not have mastered some math as knitters. Even as learned adults, if we’ve traveled through life and work experiences we have developed some basic “Math Sense.”  Many of us have “Math Muscles” that we just haven’t used for a while or on a regular basis. This doesn’t mean that we’re “Math Stupid.”

One person I spoke to defended her comments saying that she was ‘taught this by her teachers’ (whom by the way I hope are roasting over some slow hot fire somewhere for making these statements in front of students).   I have to say it once and a million times.  One’s ability at math has nothing to do with their gender!  And even if you were taught this, don’t share it to younger people. PLEASE DON’T. It still can affect others self-perceptions of their abilities. Or if you do, preface or follow your self-deprecating comment with: “I’m not as strong at math, but this may be because my teachers were insensitive and ignorant, and they screwed up big time when they were teaching me.”

If I go back to that one teacher who told me that I didn’t need to learn math… because I was a girl. Even though I knew what she was saying was wrong, it still had an effect on me to some extent. Later, I remember opting not to take higher math courses or even statistics in College, because I really didn’t think it was that useful. I also knew that math wasn’t my strongest subject and I decided to skip it. I’m not that good at it, so I’ll let it pass. Later in graduate school, I really regretted not taking that statistics class.

I’m quite a fan of the following book: Math Doesn’t Suck, by Danica McKellar.  I wrote a brief book review here. The book was written for Middle School girls, and it’s purpose was to walk girls through some basic pre-algebra concepts and provide examples that demonstrate that girls can master and do quite well in math.  I also liked the stories included in the book that featured young women who discovered entered fields where they used their mathematical know-how in their careers. Plus, Ms. McKellar is a great role model for young women pursuing careers in Mathematics, besides having an active career in Hollywood,  she continues to be an advocate for Mathematics education and achievement for girls and women. It looks like she’s authored another book called Kiss My Math.  I love it when women have an ‘attitude’ about their smarts.
