Exit ticket poster with stickies! I really like this exit ticket poster idea. This is a great classroom procedure to implement at the end of the day to assess what the students learned that particular day.
It's called a "Blurt Chart". If students blurt out they take a happy face off the chart (they are velcroed on). They have 3 chances throughout the day. You can take minutes away from recess, etc. for each happy face taken off the chart.
