we love window crayons and use them to write our sight words we are working on http://lettersnumbersandbooksohmy.blogspot.com/search/label/daily%20reading%20and%20writing%20practice
Thanks for the idea! I'm clicking on your link to buy them for a road trip!
Window crayons! What a great idea.
Kate, are you going to use them in the car? I think that's a great idea, but just so you know, the crayons come off windows really well but I'm not sure about the inside of a car.
