The school house rock video does wonders. So many of my students sing those songs way after I show the video.
I also use a lot of picture books:
Nouns- June 29, 1999 by David Weisner I give students a grid with three colums, one for person, one for place, one for thing. Then as I am reading aloud, they need to fill in the grid. This book book is full of them.
Nouns- Nouns in the News is another activity I do. I put my students in groups of 2-3 students. I give them a noun key giving points for each type of noun. 1 pnt. for singular, 2 pnt. for plural and 3 point for possessive. Then I give them a newspaper. They need to cut out the different types of nouns and glue them on chart paper. Then each group adds up how many points they have.
Verbs- We play verb charades. I put verbs on notecards and students have to act them out. This gets the point across that verbs are actions-things you can do.
I also use The Z was Zapped by Chris Van Allsburg this book is perfect for verbs and adverbs. Students have to guess what each letter is doing before I read the page.
For helping verbs, we learn the Helper Verb song (sung to Barney song) They hate this at first, but I always here them singing it.
Have Has Had
Do Does Did
Be am is are was were been
Can Could Shall Should
Will would May
Might must being are the helping verbs we're singing.
For Adjectives- I use a lot of poems.
We also do an appetizing adjective activity.
I give each stuent a paper plate to write on. Then I give them different items, for example, hershey kiss, sour patch kid, cheetos, marshmallow, peanuts, etc. They have to eat the hershey kiss, then on their paper plate record adjectives to describe it-- what it looks like, smells like, tastes like, etc. They love this activity.
I can't think of anything else write now. I will look through my binder when I get back to school. There is also a Scholastic book I think it is Parts of Speech Poetry, they give different poems for each part of speech.
Good Luck.
