This set of task card includes a 4 posters defining verb, action verb, linking verb, and helping verb along with examples and 36 different task cards. The first 12 cards have complete sentences and the student has to pick out the verbs. The next 12 cards have blanks where the student needs to fill in a verb to make a complete sentence. The last 12 cards provide just the verb(s) and the student has to create her own sentence.
These cards are geared towards middle school students, but would be a great way to differentiate if you have some advanced students in the upper elementary grades.
This could be used as homework, extra credit, classroom assignments, Daily 5, and anything else you can think of for your classroom!
