I created these flip books for my 2nd grade students to help them grasp plural nouns. There are a couple of ways to use these. You could just have them cut out, match the cover with the plural nouns of that type and glue into their notebooks. You could also use the last page where the plural nouns are all mixed up and have them cut, sort, and glue to the blank page and then match with the cover page that names that sort of plural noun. Either way, I'm sure they will learn a lot.
