These bright and colorful owl posters are the perfect addition to any elementary classroom. Starting in the billions period, each period uses the same owl and color scheme, then as each period changes, a new color and owl are incorporated until your students reach thousandths. Each poster fits an 8 1/2 x 11 inch piece of regular copy paper, with about a half inch to spare around the border, so you could make it a tad smaller if you wanted to. These are meant to be displayed on your classroom wall horizontally, ideally taking that space above your chalkboard or long bulletin board. It is a colorful display that will be used by your students over and over again throughout the year!
