Have the children help with daily meals and snacks. Do any cutting, heating or other potentially dangerous part of the cooking, but allow children to read directions, measure, pour, stir and shape. Link your food to books or other activities, creating food that looks likes characters or otherwise relates to your camp. You can also use cooking time to talk about nutrition or teach children about healthy or better-tasting substitutions for junk foods.
Spend a week or two rehearsing and preparing a performance for families. If you do not wish to write your own story with children, rewrite a well-known fable or use a pre-existing theater script. Include supplemental activities throughout the week that cover a variety of developmental areas by creating simple costumes and sets, teaching a dance, making tickets for family members and measuring the space to be used for set pieces.
Start a reading club for children to participate in throughout the summer. Give each child a membership card with his picture on it, and help him set goals for the number of books that he wants to read each week or cumulatively for the summer. Put children's names or pictures on a reading wall as they reach their goals. Give each student a book once he has reached a large goal. Plan field trips to the library or local book stores throughout the summer to support this activity.
Have the children keep a journal of their activities over the summer. Depending on their interests and writing skills, allow them to draw or write about their days, and encourage them to paste souvenirs from field trips in the book. You may purchase hardbound blank journals from education supply stores or hobby stores, or create some by placing a stack of paper between two pieces of card stock and stapling along one edge.
