Ashley - ASH96011 Smart Poly Stop Light Behavior Mini Bulletin Board Set teaches young students about their emotions by grouping them into four zones: Blue (rest area), Green (good to go), Yellow (slow down) and Red (Alert! Stop!). Write-on/wipe-off surface lets you write directly on the board and quickly wipes clean for your next idea. No lamination is needed.

Use with dry-erase or water-based markers and washable crayons for interactive play and educational development. Each colorful, 45-set includes pictures of real children's faces showing the emotion listed below as well as helpful tips for each zone.
