Mindfulness sessions are used to help raise children's awareness of the here and now. This awareness helps them cope better with their thoughts and their emotions. One example of a mindfulness exercise is the use of a glitter jar. The glitter is used as a metaphor for our thoughts and feelings.
Directions: Shake the glitter globe and explain that when our minds are racing, our thoughts are like these beautiful bits of glitter swirling all around. Then encourage students to watch the glitter settle to the bottom and to allow their thoughts and feelings to do the same. Explain that when we are still and focus on our breath we can allow our minds to calm down. This helps us to see "clearly".
