1. Day 8: Polynomials Goal: To simplify polynomial expression by multiplying. Standard: 9.2.3.2 – Add, subtract and multiply polynomials; divide a polynomial by a polynomial of equal or lower degree. Guiding Question: How can I multiply polynomials? Materials: Pencil, Folder, Student Packet 1

2. Solve the proportion: "Make sure x is in the numerator and solve" Find 10%, 20%, 50% and 100%: 65 "Find 10% by moving the decimal one place, and use it to find the others.” Percent Problems: 45 is 33% of what number? "Write an equation, is =, of x, and solve for x." Reflection Starters: “I know……” or “I need to work on……” Menta l Math Math Review Day 8 2
