Start gearing up for school with a free book from Barnes and Noble. Download their summer reading journal to get started.
This one isn't just for kids, but parents, too. Build with wood and learn new skills at Home Depot's free workshops. Most of the workshops take place Saturday mornings.
Even though these are free, you have to sign up online.
If you don't want to leave home, try camping in the backyard or running through the sprinklers to cool down.
