This game is perfect for smartboards for younger classes, and excellent for individual computers for grades 2-3. It introduces kids to different types of rhymes like raps and odes. It uses words and pictures to complete rhymes, and the sounds and the growling of the mayor when students select the right answer will keep kids interested in this activity all year.
When I had my own class, students literally cheered when I announced they would be playing this game. It is definitely one to keep in your toolbox.
