Who doesn't love the "Schoolhouse Rock" (copyrighted) cartoon series? My 8th grade students enjoy watching it just as much as any elementary school students do! I use this worksheet as students view the "Grammar Rock" cartoons to have them interact with the videos.
"Grammar Rock" is a great introduction to the parts of speech for younger grades, and is a fantastic way to review the parts of speech for older grades. For older grades especially, these videos are a perfect way to make reviewing grammar fun--I always encourage singing along!
Many of the Schoolhouse Rock videos are available on YouTube for free; I purchased the entire Schoolhouse Rock series on DVD for under $20. Feel free to view all the videos in order, to view a few at a time, or to use one-by-one as you work through the parts of speech.
