Mouse Mischief - Free tool lets students participate during class

What Is It?
Mouse Mischief is a free tool from Microsoft that you can add to PowerPoint to allow multiple students to participate in your presentations.  You can add multiple choice, true/false, yes/no, or drawing question into your presentation and the students can use any computer mouse to answer questions. 

How Do I Get It ?
All you have to do is go to http://www.microsoft.com/multipoint/mouse-mischief/ and download the application.  Once it is installed, you will see a new toolbar for Mouse Mischief in the PowerPoint ribbon.  Now, when you open a PowerPoint presentation, you will be able to add interactive items very easily.

Can I See It In Action?
