Maybe you need table numbers. I know I did, being a special area teacher who sees some kids every day and some kids once a week. But honestly, I needed table numbers when I was a regular classroom teacher, too.
These cute table numbers feature two numbers per page. They are tiny navy and white chevron with a green foreground and white numbers. They are easy to read, even hanging from the ceiling like mine (see pic!). Use them for center numbers, too!
