Right now I'm absolutely MAD about the combination of orange, gray, and chevron. This is reflected in my newest set of the cutest little word wall cards. These will be on my bulletin board this year!
Included in the sale are all 26 lowercase letters of the alphabet on 3" x 3" squares. I use a set like these for my word wall, but you could use them for just about anything! Simply print on card stock, cut out, laminate, and they'll be a great addition to your classroom.
