The hundreds chart is a great visual aid, because it really gives you a good idea of how base ten works. You can easily see the patterns that you know about (like counting by tens, starting at any number, ie 6, 16, 26, 36, 46...). I know it seems ridiculously simple to some people, but sometimes we just need to be able to actually see the pattern in front of us to get it, you know what I mean? I didn't see a hundreds chart until I was and adult, an it would have made math so much faster for me as a kid! Like I said, I was good enough at math to be in advanced classes, but that's only because I could memorize algorithms, not because I understood the concepts.
There are other patterns that are easier to see when you look at the chart, like combinations of 10, for example. 4+6=10, 14+6=20, 24+6=30, etc. Does the visual aid help you to see the patterns at all?
