These sentences can be used in a number of ways in your classroom. I like to use them to play Scoot or as a center activity.
For centers, I cut out all the sentence strips and put them in a brown bag. Students take turns pulling out a sentence then determine whether it is a fragment, run-on or it is complete. If the sentence is anything but complete, they correct it on a separate page (included).
I hope you can find this useful in your classroom!
