Printable - Goes with NOT-A- BOX, an excellent book about creative thinking. I cut out colored squares and rectangles, glued them to white paper and handed them out to students after reading the book. Then i would ask the kids to turn it into "not a box!
Great Visualize think sheet -Often kids just hear what is being said but not actually listen. This will help them make a mental picture and develop visualization. High school kids like to draw & color, too!
