Consider these three tips from Scholastic for keeping kids motivated all summer long.

1. Set aside time each day to read. Track the books your child reads and reward him or her with a special activity or treat when he or she reaches milestones (for example, every 10th book). Do art projects based on favorite titles, such as making paper bag puppets.
2. Make every day educational. Children learn problem-solving, math, science, and vocabulary as they help with groceries, laundry, and cooking.
3. Create a summer scrapbook. Save postcards and movie tickets, record family stories or interesting events from each day, whether you’re going on vacation or just going to your neighborhood park.
