This classroom number chart includes numbers 0 - 20 and includes both tally marks and ten frames. This set includes two sizes to choose from, so you are getting two sets with this purchase. Choose from full page posters (8.5 x 11) or 6.5 x 6.5 for smaller spaces, or display both. Both sets are solid, multi-colored chevron and alternate 5 colors that include turquoise, pink, purple, lime green, and yellow. These posters coordinate with my other "Chevron Brights," so be sure to look for other "Chevron Brights" decor in my store to match!
