Here's a cool idea for the whole family.  Reusable scratch paper that lets you save paper while you doodle, sketch, make lists, take notes, or draw. Created by college students who wanted better tools for graphing, sketching, and charting their way through courses, these dry erase pages come in a variety of styles.  Many of the sheets are geared toward science students (such as the Organic Chemistry Reaction Table Sheet or the Cardiovascular Physiology Guide) but blank sheets would be perfect for any student...kindergarten or college...and a great way to take and leave notes around the house.  Check it out:
