This is a fun chant I used with some EL 2nd graders to reach antonyms. The chant is divided into A and B parts so you could have two sides of the room say each part. I always start reading it all aloud however.
Here is how the chant starts. "Antonyms are opposites and opposites are fun. Come along and chant a song and you'll learn some."
I really enjoy using chants and rhymes in my classes and I hope you will too.
