This past weekend I was reading chapter 5 in Marzano's Art and Science of Teaching on student engagement. There are many ways to engage students in our classrooms. Games are one way to focus on academic content. I would like to recommend a free application from David Riley who lives in the United Kingdom.
Triptico is an IWB tool that is downloaded to your computer. There are 22 resources to use in your classroom. I read in his blog that teachers from K-high school are using Triptico in their classrooms. While this is designed to be used with an IWB, you can still use it with a projector and have a student be at your computer to use the resource with the class.
You will need to visit Triptico to download onto your computer. I do believe you will need to download Adobe Air prior to downloading and installing Triptico.
