Library of Virtual Manipulatives

I am teaching mathematics for elementary education majors this semester, and we are currently discussing number systems. In discussing our base ten number system, I found the Library of Virtual Manipulative’s section on base blocks to be extremely useful. It turns out that it takes much less time to click on a button to create a virtual 10-by-10-by-10 cube than it does to build an actual 10-by-10-by-10 cube. This allowed me to run through many examples in class.
