Printable Round Letters for Classroom! These are great for Word Walls, Bulletin Boards, and more! As a teacher myself, I know that often times our schools do not provide us with color printing access or it's not as readily available. I wanted something I could easily print (even from my classroom) but still be able to incorporate color if I wanted to. So, instead of printing these in color, I used colored paper to print them. They turned out fantastic! The size of each circle/letter is 4.25 x 4.
