Here is a lesson plan on using linking verbs, which is the first part of two lessons on using these kinds of verbs with predicate adjectives. This is a very common syntactical structure in English, so I have a number of lessons, using a number of strategies and parts of speech, that aim to help students develop their own mastery over this kind of sentence.
I open this lesson with this Cultural Literacy worksheet on intransitive verbs; in the event that the lesson goes into a second day, I keep this homophones worksheet on the adjectives hardy and hearty nearby. This learning support is a word bank of predicate adjectives to use with this scaffolded worksheet that is the center of the lesson. Finally, here is the teacher’s copy of the worksheet.
