My students have a difficult time with verbs. This poster helps them understand that all verbs are action verbs or linking verbs. Within that, it lists many action verbs and all state of being verbs. Within state of being verbs, it shows that there are helping verbs and linking verbs with examples of each.
The part of the poster that I like best is the "Imposter" portion, which are called verbals. Students get so confused with participles, gerunds, and infinitives. This poster defines and points out examples for each.
