The Little Things: Testing Motivational Treats. My students have enjoyed this type of treat for several years. Every morning of a 'big' test, there's a treat with a little note waiting for them at their tables.
This is a great activity for practicing pre-writing skills such as "down", "over", "around", etc., shapes, and even more advanced writing skills - like letters. In addition, it offers a great therapeutic/calming effect for some children and can be a sensory activity just for the sake of sensory.
