I have created a synonyms units. There are 3 multiple choice pretests/posttests that each have 9 questions. There is a set of mini practice for synonyms for Monday through Friday. Three days each have 5 open ended questions. One day has a paragraph that students rewrite with new synonyms from a word box. The last day has a word puzzle to put synonyms into. There is also five practice pages that each have 5 multiple choice questions.
I teach in VA where this matches SOL 3.4b synonyms.
