Camping Preschool Activities, Games, Crafts, and Printables. Summer is a time for camping out under the stars, snuggling up in sleeping bags, and roasting marshmallows over a campfire! This month's theme offers a mountain of ideas for bringing the fun of camping into the classroom. Included are activities and games that develop literacy, increase vocabulary, teach math concepts, and spotlight the wonders of nature. Children count, add, subtract, problem solve, read, listen, write, match, sing, act, move, exercise, and more!
