If you want some help to make every aspect of your classroom a true learning experience then you will love the "Math Clock". I have seen several for sale on the web, but they are outrageous so I decided to use my computer and make my own. All you need is a computer, printer, and a cheap clock from a yard sale. It's so much better than investing the $30+ in a pre-made one and you have the ability to make it your very own. To dress it up even more I printed mine on a piece of graph paper as you can see in the preview.
