This core vocabulary board uses 3"x 3" pictures to be used as a large core vocabulary board for the classroom. My classrooms use this for aided language stimulation and visual aids. It contains core vocabulary that I complete lessons for in the classroom (lessons will be for sale soon!). This board has 40 core vocabulary phrases. We put magnets on the back of ours and attach it to our white board. The board itself contains white squares to include scaffolding at your own pace.
