I have trouble supplementing with math, though. What are good suggestions for this?
First, don't think "math", instead think "critical and analytic thinking"
All those other things are great for those skills, too! You don't need to do workbooks to develop a better math mind. Getting him out in the real world and seeing how math and science are useful and important will do a lot more to help him in the long run than more worksheets. You still haven't said how old he is, so some of these may be inappropriate, but here are some ideas for helping with math/critical thinking/analytic
Our library has a lego night every month. Great for helping to develop spatial skills, which is a fundamental math skill. (See, there are a million and one reasons to hang out at the library!)
Does your school have a chess club? If not, help start one - very little expense! Or buy him "no stress chess" and let him learn.
When you're cooking, make him figure out the fractions to double or halve the recipe.
You can't get to the moon without math - spend a lot of time at the Air and Space Museum, especially in their hands-on room.
When you read the newspaper or listen to the news, (or really anything), and they mention a statistic, talk about it. What does it really mean? What did it really measure? How do you think they figured out that number?
If you really want to focus on "school" math skills. Make sure he memorizes his multiplication tables. Not just "knows them to pass the test" but knows them as well as he knows his phone number.
I don't think there is a single other skill that will have that much payoff. Doing fractions, algebra, even calculus will be that much easier if he doesn't have to think about his times tables.
