Today's Gratitude Item: My iPad. One of my students was quite literally clowning around in my junior Math class (the behaviour was completely unacceptable). I snapped a photo of him and emailed it to his parents. Guess who is grounded this weekend! Said student also got to spend some quality time with me at lunch.
