Hello everyone, I just joined. I shared a web link with the host of the MathIsFun website, and he suggested I share with this forum. However, the forum won't accept links, so just Google "Taking Heron's Fortress" Full disclosure: Skye is my son, but I hope you agree it's still a cool thing to share (set YouTube to HD so you can read formulas). FYI, I'm the only teacher Skye has ever had, and my approach is pretty simple: We start with the best books for us that was Lial for Algebra I & II, then Barnett for Trig, now Swokowski for calculus. Then we take our time, and always keep in mind there are two levels to learn: how to get the right answer, and what's happening "under the surface". We never drill - we only enjoy ourselves!

Hi louhawthorne!

Welcome to the forum!

I'm glad you don't drill and would rather enjoy yourself. Me, I personally have high emphasis (on myself) to understand everything (I'm still having some trouble with calculus, but getting better...). As for the link you are talking about, looking up on google like you mentioned, are you talking about http://www.youtube.com/watch?v=9qSxWvIcmAI? Because I'm not sure what you mean by it doesn't work on the forum...

Hi;

Welcome to the forum!

hi louhawthorne

Welcome to the forum!

I have just finished watching Skye's presentation of the proof of Heron's formula.

Please tell Skye I am awarding him a gold star!

Really impressive.

I see, also, that You Tube is encouraging me to watch another on the binomial theorem. Indeed I shall.

ps. Make some more posts. The web link bar is to prevent spam. It goes away once you move from Novice to Member.

Oh, so novices can't post web links?

Hi;

Yes, you have to be member first and then after a certain time period has passed.
