Math Live, online animated math tutorials from LearnAlberta.CA
link
This free site features 23 different interactive tutorials on a range of math concepts. The focus is on understanding concepts, not drill. The tutorials are "taught" by friendly animated characters-- it's not as fun as Cyberchase, but it's not too dry either.
The topics covered are: decimals, fractions, basic geometry, plotting points on an XY coordinate system, and probability. If there's a topic that your child isn't getting or is resistant to being taught, this could be a helpful site.
