Let me begin by saying I'm not a huge fan of rewarding with food (in the classroom or at home) but once in a while, a little treat can make the day a little more sweet.
I've done these little testing encouragers for a while, and I've found some wonderful ideas online, but last year was the first year I made all of my own.
My students have 6 individual tests (2 math, 2 reading, 2 writing) so I made up 6 little printables for them with the matching candies. I was able to get all these candies from the Dollar Store, and 2 bags of each were more than enough for my class. Before the students came into the classroom each day, I had their testing booklets out, a new sharpened pencil and eraser on their desk, and one of the little treats set out. I also like to display an encouraging quote over the whiteboard during the test, as well.
I've uploaded a copy of all these encouragement notes to google docs if you'd like a copy of them. Click HERE or on the picture to get the link. There are 12 cards per sheet for easy printing. (Since my two oldest girls are also in a testing year this year, I'll be slipping these into their lunch bags, as well). I also have a pin board of Testing Encouragement Ideas you can see HERE.
