How many students voted for each color?  Point to and read the categories Red, Blue, and Green.  You can record your numbers on the lines.  Prompt if needed:  How many students voted for red?  How many voted for blue?  How many voted for green? 

·         Compare your categories.  How many more students like red than green?  Show your thinking with pictures, numbers, or words.
