This is an acrostic poem activity and can be used as a creative review of adjectives, as well as synonyms. Review the meaning of both and have students choose descriptive words to describe the topics. They can use single words, phrases or full sentences beginning with the first letter on each line. (It doesn't have to rhyme). Also encourage students to find similar words of those chosen to help them understand and use synonyms.
Extend the activity by having students create their own poem choosing their name or a favorite thing or something that is important to them. Have them share their poems with the class.
