Khan Academy is a non-profit website site where you can access free online math, science and finance lectures. When you visit you'll see subjects under group headings like Algebra, Trigonometry, Calculus, Physics, Chemistry, SAT Preparation, and Arithmetic.
Under each subject, such as Arithmetic, are listed all the topics, such as Dividing Decimal Numbers. Click on the link and you'll be taken to a YouTube video, such as this one here.
Khan Academy looks like a really amazing resource. Not only are there all the video lectures, but there is also a curriculum, with exercises to work, for some of the math topics, including Arithmetic and Algebra 1. Here is the link to the Khan adaptive math program. I didn't go in and look to see how the exercises are presented because you have to register for that part, but I recommend you check it out if you're looking for a new way to do math.
Now I'm wondering if I could have avoided some of the $$$ I've spent on math curricula over the last 6 years of homeschooling...
