If you didn't start out your year (all grade levels) discussing bucket filling, go back. it's not too late! For great anchor chart activity to go with the book: Have You Filled a Bucket Today? Teach your students compassion and empathy.
Have You Filled Your Bucket Today? Students fill each other& buckets with pom poms when they witness a student doing something helpful or kind. When their bucket is full, that student will receive a sticker on a chart to commemorate their achievement.
