Be thankful! Appreciation is the quality of being thankful and the ability to appreciate and return kindness.
Assembly Read Aloud: The Thankful Book by Todd Parr
I am thankful for music because it makes me want to dance.
I am thankful for my feet because they help me run and play.
I am thankful for kisses because they make me feel loved.

Activities:

• Thank You Circle: Using a talking stick, the leader thanks the person next to him/her for an act of kindness or a positive personality trait. That person says, “You’re welcome!” and thanks the next person for something, etc.
• A-Z Gratitude Game: Students sit in a circle. Assign a leader (yourself, or one of the students) to start. The person starting should say something that he/she is grateful for that starts with the letter “A.” The next person should say something that he/she is grateful for, starting with the letter “B.” End the round when you have covered the entire alphabet. Variations: students use the first letter of their names; select a theme of gratitude (gratitude for people, things, ideas, etc.).
