Bucket Filler is great! However, it can be hard to find the balance between cognitively appropriate and age appropriate with materials for our high school students. I made this power point to show my students prior to writing each other nice notes to practice being a Bucket Filler. I do this lesson in the classroom with classroom staff so it can carry over into every day! Slides include animation and some voice over to increase participation and engagement.
I pair one of my slides with the cards from School Counseling is Magical's Bucket Filler Board Game https://www.teacherspayteachers.com/Product/Bucket-Filler-Board-Game-1288513
