Here's a great game to play with your students to increase their vocabulary. It's called I Have - Who Has. Pass out the cards and then have them read the descriptive question on their card, the person who has the match responds and then reads their description. It goes around the room like this until you get back to the first card. Super fun!
This is a 32 card set of Synonyms AND a set of 32 card set of Antonyms. The skill level is set about a third, fourth, or fifth grade vocabulary level. Use them on a rainy day for indoor recess or bring them out before the big standardized test. These cards make them think of the different meanings behind each word.
