We have been working a lot -- and I mean A LOT -- with suffixes this year. This activity uses words from the book, Happy Endings, A Story About Suffixes, by Robin Pulver, to review what we've learned. Instead of giving the students categories for sorting words, I am only giving them the words. They have to come up with the categories, create their own graphic organizer, and write a few sentences using these words. It is correlated to second and third grade Common Core Standards.
