At the Title 1 Parent Meeting participating parents were interested in a free website their children could use to practice math facts and skills over the summer. After talking with K-4 teachers sumdog.com was suggested. Sumdog is a learning website for ages 5-14. It allows a child to play games while simultaneously bettering their math and other academic skills. It is easy to sign in to - I tried it and didn't have any problems. I even played a few games! Of course, I would encourage you to limit your child's screen time this summer but when appropriate this would be a recommended website.
Have a great summer,
