1 P1 Summer Math Review Packet For Students entering Geometry The problems in this packet are designed to help you review topics from previous mathematics courses that are important to your success in Geometry. Please do each problem and show the work that supports that answer. This packet will be collected and graded the first week of school. There will also be a test over this material the first week of school. It will be your first test grade. There are no retakes on this test. Enjoy your summer! We look forward to seeing you in August! Basic Fraction and Integer Operations (No calculators please!) Simplify. Leave each answer as reduced fractions (no decimals). Show all work ¾ ½ (- 18) ( 14) 11. (-5) ( ) ( 3) 16.
