Level 7 (Course 2) – Summer Math Packet – Parent Info & Answer Key Parents’ Information Page Math is a cumulative discipline; each course builds upon previous concepts with more complexity, more integration, and more independent work. This Summer Math Packet was created to provide extra practice on needed skills to enhance your child’s success in the coming school year.

Here are some ways you can support your child’s efforts:

 Please review the Summer Math Packet with your child.

 Help your child create a timeline for work completion. Your child should complete one unit before moving on to the next. These units do NOT include an entire year’s curriculum. The objectives were carefully chosen to highlight key concepts in the 7th grade curriculum.

 Provide a quiet, organized work space to help your child stay focused.

 It’s ok if you or other adults provide assistance.

 Calculators should not be used unless otherwise indicated.

 Try to make time to review your child’s work at the end of each unit. o Answer sheets are included in this parent information packet.

 Remind your child to return their Summer Math Packet to their math teacher the first week of school.
