Classroom reward system- If the class shows great behavior, they will get to color in a letter tile of their choice. When every tile is colored in, the students will win that specific award. I just googled "Scrabble Font" and downloaded it for free. :)
quiet critters-when you decide it is important for students to be quiet pass out quiet critters- take them away from students who talk. At the end of the activity anyone who still has a quiet critter gets a prize, point, whatever you use.
