"The Decimal Number Line tool allows teachers to display and interact with a number line. The number line can be moved around and zoomed bigger or smaller. Teachers can decide on which units are displayed and also whether unit marks are displayed. What's really cool is that teachers and students can move an arrow back and forth above the number and when they're ready, they can touch above the arrow to reveal the arrow's location on the number line. The number can be turned off and on just by touching above the arrow. " description by Jim Hollis
