Ixl.com has lessons for PreK through Algebra. The list of skills that can be practiced on each level is vast. Some examples include: patterns, money, geometry, fractions, algebra, coordinate graphs, charts, logical reasoning and decimals.
Ixl.com has an adaptive learning system, where the difficulty of the questions increases as the children's skills improve.
I'm trying to find math that I can easily tailor to my son, since neither of us has the patience for Saxon and the public school book we are using breaks down everything into miniscule bits that seem to make the concepts more confusing instead of less. IXL looks promising. It has all the state core standards ("just the facts, ma'am"), with samples listed if you hover your mouse over each heading, so you'll know what they're talking about. Worksheets are available in each category . If parents wish to join, membership is $9.95 a month and allows children to do their work onsite and be tracked by IXL teachers. Otherwise, they can just use it for reference (which is what I'm doing) to find the specific areas where their children need help and just work on those.
There are also other subjects available by entering key words in the search box.
