Name: Score: MHCA Math Summer Packet For students entering Algebra I CP The Summer Packet is broken into 10 different sections labeled weeks with 10 questions in each section. If you do one section a week, you can complete the entire packet before the start of the school year without much stress. This will be collected during the school s Orientation Days (August 28 th & 29 th ). Packets turned in on the 1 st official day of school will lose 10 points for being late. Any packet that is not turned in by the 1 st day of school will receive a 0. The summer packet counts as a double quiz grade, and will help you review the material from last year so it is in your best interest to complete the packet. If you have any questions regarding the completion of the MHCA Math Summer Packet please contact Mrs. Magrogan (gmagrogan@maryhelp.org) or Mr. McMahon (fmcmahon@maryhelp.org). Here are some websites to help you with the summer packets. Typing the topic into a web search will also give you more websites to help you. http://www.khanacademy.org/ http://www.math.com/ http://www.coolmath.com/ http://www.ixl.com/math/grade-7 http://www.themathpage.com http://www.mathgoodies.com http://www.math-play.com/integers-game.html http://www.purplemath.com/
