Lost in Wonderland, that's what grammar can feel like for kids, (and adults!). I'm always looking for easy and fun ways to help kids reinforce skills that need lots, and lots of practice. I found some terrific games (below) that should help, plus I have a couple of freebies for adjectives and adverbs (click on the link below the pictures). One is for second grade (primarily), and one is for third (again, primarily). With the different requirements in different states, you just never know what a particular grade's needs are. In any event, I hope they help you out!
Need some games?
Great grammar games are on this site, including this one called Verb Viper and Word Invation.
The kids have to be FAST to catch the words with this game, but it is fun! Plus it's one of the things on Brain Pop that is free! (Always a plus!)
Don't miss Grammar Ninja! Great sound and wonderful practice.
