The Outside Play and Learning Book, by Karen Miller
This one really came in handy for that outside play time when you just want to add a little structure to it! Some great activities for preschoolers! It’s sectioned into themes, like “The Wonderful World of Make-Believe,” “Wheels, Wheels, Wheels,” “Dig It-Things to do with Sand & Mud,” & much more! And each activity tells what age its appropriate for as well as what materials are needed, what to do, what to do for more, and what they can learn from the activity.
