Crazy for First Grade: Differentiating Math!- i chose this for the chart, but you can use it to differentiate instruction (have one student draw, have another outline, etc.) but it's also pretty cool because it has a math lesson too
DIY: Mail/Paper organizer from cereal boxes. Duct tape to make the seams of the box sturdy and using mod podge dress the box with some cute scrapbook paper. LOVE this for over the back pack hooks for all 4 kids homework.
