Hi Team!

I have listened to a few general podcasts and I like Greg's idea to start and end with some background music. Here are some that I found:

=QF PODCAST 1=

Here is a great template!!!! PERHAPS THE BEST one, this one has the song and lists the different methods of how to solve quadratics and when to use them!! [|OUR IDEA - the song] it contains some good ideas of things to add to ours. I liked it!! BEST SO FAR!

(I liked the above podcast too. If we can do intro music, it would be cool. it adds a nice touch. The graphics were also neat. Something like that would really grab the students attention and keep it! Sue) = Student podcast = This is a kid solving problems using the QF.

[|Quadratic Formula Podcast 2] On this one, the visuals are very small but if you just listen it takes you through the quadratic formula. It seems like the site owner was planning on making more podcasts but I could only find this one.

( I could not get the above one to play, sue)

=Index of different math podcasts= This contains several podcasts by the same guy: [|List of Math podcasts]

Here's another example of a [|Student podcast with video].

What are your thoughts of the podcast contents that we create besides the beginning/end music and singing of the formula?

NOTES Often, the simplest way to solve ax^2 + bx + c = 0 for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it does not factor at all, or you just do not feel like factoring. So, while factoring may not always be successful, the Quadratic Formula can always find the solution.

The Quadratic Formula (words to song sung to tune "Pop goes the Weasel"): x equals negative b, plus or minus square root of b squared minus four ac, all over 2a.

I think a little background info is good, mentioning the different ways to solve quadratics. Perhaps we can actually run through the simplification of the equation, using an example, pointing out some possible trouble areas like: a) make sure to take negative coefficients with a, b and c when substituting in, b) simplifying the radical correctly (is -4ac positive or negative? be careful!) c) simplifying the rational expression, ie cancelling out of both terms if possible, not just the first term in the numerator and the denominator.

I liked how in the first example above the teacher repeated the song to have the student sing along, to help memorization.

Do you think we should include any examples on this?
