Another pinner said Seusstastic Classroom Inspirations: Word Work. Students place the lily pad "sight words" or any word families around the room and say them as they hop on each word. I can see adapting this for any math skill as well!
Erin: This bulletin board can be developed throughout the year to help students learn vocabulary. Once the students become familiar with learned prefixes, roots, and suffixes, they can continuously add more examples (leaves) throughout the year!
