We’ve always been big fans of Scratch Magic from Scratch Art Co. — it’s a fun craft activity that’s easy to explore and works for a range of ages.  You start off with a black sheet and with the enclosed wooden stylus–you scratch off the black to reveal the print or colors hidden beneath the blank overlay.  You can draw your own design or use the enclosed stencils.  This deluxe set, Wacky Scratch Deluxe Kit $15.99,  comes with sixteen drawing boards (trust me you will want to try this yourself), stencils and three frames for displaying your work.  They also make travel sized sets—  useful and easy to take along when you need your kids to be entertained, sitting down and quiet (at least for a little bit!). You can also buy this bigger kit and break it up into small sets to dole out as you go.  Also a good to choice to have in your office for when your kids drop by and you have some work to do.
