Numbers 1-20 to add some color to your classroom! I have laminated these and put magnets on the back of mine, and they are currently on my whiteboard! I have used these when we learn about a certain number, or when we are practicing counting.
I have also used these as game starters, each student gets a number and they have to work together to get in order from 1-20.
My classroom is a very simple theme of rainbow, mainly as borders.
This is one of many rainbow items I have, so take a look at the other ones to help coordinate other areas of your classroom!
