These posters are for classroom decor and student references. They are bright, clear, and easy to read from across the room. I also like to print two to each page to make smaller versions. This help conserve space in our room. These match the number, alphabet, 2-D and 3-D shape posters that are also in my store. Each color comes in two shapes. The first shape is slightly smaller than 8.5 x 11 paper and has rounded corner. These take more time to cut out but look really nice hung up. The other size is a regular 8.5 x 11 paper.
