What certificate or proof will you provide after kids finishing the 7th Grade math on your site?
My son's school need a prove of him finishing 7th Grade math during the summer, so he can be placed in 8th Grade math class. what certificate or prove will he get after he finishing the 7th Grade math on your site?
Education.com doesn't offer a math program or course online. However, there are resources I can share with you to help your son with his math learning over the summer. Specifically...
Stanford EPGY Math is designed for students in kindergarten through middle school, and is available to all families looking to boost their children’s academic performance. You can learn more about it here: http://www.education.com/e-learning/stanford-epgy/
If you plan to do Education.com activities together this summer, consider joining the 2010 Summer Activities Challenge for a chance at great prizes, including a family vacation to Mexico! http://www.education.com/summer-activities-challenge/ If you complete 10 activities in the Challenge, your family will receive a certificate of achievement (however, this is not certification that your child has completed 7th grade math, and instead is intended to celebrate your family's achievement in doing learning activities together over the summer).
I also suggest contacting the school or school district for referral to programs or courses that would meet their requirements for advancing your son. If you don't have the school or district's phone number handy, you can use SchoolFinder to research it: http://www.education.com/schoolfinder
I'm including some additional information resources below that you may also find helpful. Thanks for asking!
