Sheppard Software (http://www.sheppardsoftware.com/math.htm) is a fun and free computer game website to use in large group, small group, or individual engagement. Use on your classroom SmartBoard for group interaction or computer for individual use. I have used it in both settings with my students as well as pause during games to provide additional instruction if students struggle with concepts. The coin games can be used as opportunities for students to demonstrate money IEP goals toward progress.
