Print out one of each of these templates and make a folder for each template. Make enough copies of each template for your entire class, with a few extras, and put them in the folders. Have your folders in an easy-to-reach place, so when you are teaching a lesson that lends it's self to a Bar Graph, you have them on hand! Pass them out to the students and bam-you can help your students organize their thoughts on the fly!
