This is a great reference sheet for your students to keep in their journals or folders for those tricky plural noun rules!
In my classroom, I have "Reference Folders" that each student keeps. In these folders, the students keep helpful foldables, printouts, and notes to "refer" back to during the school year. This gives my kiddos a sense of independence and teaches them to help themselves instead of constantly relying on the teacher. This particular handout DEFINITELY squelched a multitude of questions about the plural noun rules...which makes for a happy teacher and happy students!
