Behavior BINGO. setting this up THIS WEEK! Large 100 chart for the classroom, class rewards when they get BINGO. Earn 1 sticker for perfect class attendance and no tardies, or for good behavior in the hallway, etc. 2 stickers for a compliment, etc. Teacher keeps # 1-100 in a bucket and draws out when they earn a sticker, so they never know which numbers will be covered yet.
