Apangea is an online math resource partially funded by the state of Indiana. It is primarily geared towards high school students taking the Algebra I ECA, but can be used for grades 3-12 with varying content. I use Apangea as part of my math lab.
Research suggests that small-group teaching is the most effective way of having new information learned. In addition, there is plenty of evidence suggesting that reading centers that focus on specific sub-skills are an excellent approach to teaching reading, comprehension, and fluency well. Therefore, I particularly benefit from this website, as it offers a wide variety of sub-skill targeted reading centers for kiddos in grades k through 5. Again, this is a WINNER of a site (with a lot(!) of resarch to back it up)!
