I think I have come up with a solution:
In this little "mobile desk" I have post-it's, markers (and Sharpies), note paper, paper strips (perfect for language lessons!) dry erase markers and eraser, paper clips, one highlighter, two pens and two pencils. When I'm getting ready for a lesson I can just grab the box and go! How easy it will be to take it anywhere I have to give a lesson in the classroom!
