It's so important for children to get enough exercise. So why not plan out some nature exploring and nature crafts. Take sketchbooks and watercolor pencils, hike to a nature spot, and spend some time drawing things. Collect leaves and take them back for use as stencils. Sometimes it's harder in the city, but look for regional parks, beaches, lakes, and nature trails. If you are allowed to glean things, bring back flowers to press. Pine cones and pine needles are useful for many crafts. Seashells are a favorite of children everywhere. Fashion simple hair ornaments using things found in nature. Or frame seashells and leaves in shadow boxes. Many places have scheduled nature walks that are kid friendly.
