This PowerPoint is quick and fun to do with 1st and 2nd grade classes! It can be for the special occasion of Dr. Seuss' birthday, but it can also be done whenever you are teaching rhyming words. This PowerPoint goes really well when reading Dr. Seuss books.
This file contains a definition slide with examples, a slide where they choose which words rhyme out of a group of words, and several slides after that where they are given a picture and a word and they come up with words themselves that rhyme with that word. Then when you click, it gives you a word that rhymes with it to see if the kids got the same word or not.
The 1st graders I did this with loved it, and I hope you do too!
