Have your kids started the “I’m bored” chant yet? Mine have. Every summer for the last three years, we have been busy with a road trip around the United States, and that has kept the “I’m bored” chant at bay. This year though, we are not starting our annual trip until September, which means the boys are home all summer. While they are homeschooled and at home every day of the year, summer means no work to keep them busy. That’s why I love ideas like these 10 sidewalk chalk activities that are simple, cheap and can keep the boys busy for hours.
