Summer 2015 Geometry Packet
The goal of summer math is to ensure that students are prepared for their high school math classes.
The skills learned in elementary and middle schools are an integral part of success at the high school level, and
this packet covers many of the important concepts that students entering high school should have mastered.
All students entering Geometry as either a sophomore or freshmen must complete this math packet
over the summer. It is due Wednesday, September 2, 2015 (or the first day you are in school). Packets will not
be accepted late.
You will receive two grades for this packet – one quiz grade of 100% for completing all of the problems,
and another quiz grade based on the accuracy of your work and answers. Be sure to show all work to complete
the problems.
In your Geometry class, you will not be using a calculator regularly. Therefore, there is NO CALCULATOR
USE ALLOWED ON THE SUMMER PACKET. Additionally, all students will be taking a pretest the first day of
school on the information covered in this math packet, and students will not be allowed to use a calculator on
the pretest either.
For more practice on these skills, use the following internet sources:

If you lose your packet, there is a copy on the website, http://npsd.k12.ri.us/nphs/ under β€œAcademics”.
Good luck and have a great summer!

Now it is ADDITION, use the rules from above
Multiplication/Division:
If the signs are the same, the answer is POSITIVE
2
If the signs are different, the answer is NEGATIVE
