Beth in SW WA Posted May 16, 2010 Share Posted May 16, 2010 Khan Academy on Youtube KhanAcademy.org I was watching a bunch of youtube videos on Singapore math when I landed on his site. He's amazing, imho. I could have used something like this *free* service when I was in high school and college. That is all. :001_smile: Quote Link to comment Share on other sites More sharing options...
Guest Posted May 16, 2010 Share Posted May 16, 2010 This was my great find of the past couple of months too; my daughter and I couldn't figure out why x to the power -1 should be 1 over x, or how to make sense out of any number to the power zero being 1. But after watching his 4 minute clip on negative exponents we both had a huge aha! moment. We then watched the whole shebang on exponents and felt it was far better done than the textbook we are using. Has anybody used the science mini-lectures?
