Let me sing a line or two from a couple of the grammar ones: "Conjunction Junction, what's your function? Hookin' up words and phrases and clauses."
How about, "Well, every person you can know/ And every place that you can go/And anything that you can show/ You know they're nouns."
These songs are a fun way for children to become familiar with the parts of speech. We found our DVD, complete with every Schoolhouse Rock song, on e-bay. You can also locate them at Amazon or on YouTube. I'm including the ones I sang for you. : )
