This article spells it out clearly, from the perspective of a former high school teacher. The whole website is an amazing compilation of the science behind mindfulness and it's application in real life.
A quick video to show the impact that gratitude has on happiness levels. I use this to inspire students to write their own gratitude letters and read them to the recipients. It pushes kids outside of their comfort zone in an amazing way.
A mindfulness website (and app) that is perfect for use personally, but also has easy to follow and use educational programs for elementary, middle and high school students. I use this program DAILY with my middle and high school students
I love this entire website, but this article in particular because it is FULL of great ideas that can be used in any classroom. And even though it's geared towards around Thanksgiving time, I use gratitude activities all year long. The impact that gratitude has on happiness and health is amazing.
