We have an English progam called Shurley English. It teaches children jingles to learn parts of speech. There is a song for learning what a noun is. It goes to the tune of This Old Man, He played One; The words are:
This little noun
names a person, place or thing,
with a Knick, Knack, paddy wack,
These are English rules.
Isn't language fun and cool?
You could teach the song and then have a little game. Have three flower pots. Print person on one flower pot, place on one flower pot and thing on the last flower pot. Put words on some cut out flowers and let them place the flowers (words) in the correct pot.
