A fun way to learn grammar rules

I just got this and played it to get an idea of how itll work for my kids, who are in 4th and 6th grades. So far, it is great and easy to use. Its only downfall is that it seems that I will have to buy the pay version to get more activities. But, if he kids like it as much as I think they will, itll be worth it.
