Set up students to be successful on testing days with encouraging Snacks: Send 4 paper bags along with 4 index cards, and an instruction sheet home to parents. Have them fill these bags with snacks for their favorite little third grader, and to include a note of encouragement and/or pride.
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.
