These "Bird Bucks" can be used as money for a daily depositor system, calendar math, economy system or to teach place value. The bills correlate with the place value system ones through one million. Images are created to be printed onto color paper, therefore, the images are in grays, black, and white. Graphics provided by © Laura Strickland/MyCuteGraphics.com.
