In this brilliant third book in the My Teacher Hilda series, the fun picks up right after the second book, A Picnic Day. Ms. Hilda's children are in for an adventure when they go outside for activities, but not everything is bound to run smoothly... The Water Balloon Fight is a great tool for children to learn how to be safe and have fun outdoors. Children will be encouraged to listen to others, overcome their fears, try new things, help others, and so much more!
