Take advantage of a Web site that offers free grammar games. Gamezone has a lot of fun, constructive games your students can play free of charge. There's no need to set up an account with Gamezone to access the games.
Consider purchasing the Grammar Pack software program for regular use in your classroom. The pack includes the popular Grammar Quest game, Storymaker game and quiz worksheets you can print and hand out to students. The pack also includes a story builder that lets your students create their own grammar games.
Arrange a grammar party for your class. Give it a cool name like Grammar Jam. Check with the school to see if they can provide snacks. Consider using an entire day (maybe a Friday) to let the class play grammar board games and online grammar games. Have the class alternate playing the games so everyone gets to play a game related to all of the topics. Let the class know there will be a test the following Monday. You can award anyone in your class who gets a passing grade a prize.
