In this 6 lesson unit polynomials are introduced by first examining the base-10 number system. The properties of numbers are extended to polynomials to develop their sums and differences. Multiplication of polynomials is emphasized. Products are then reversed in the process of factoring. Students become fluent in all major types of factoring, including difference of perfect squares, gcf, and trinomial.To access the lesson videos on YouTube use your smartphone or tablet to scan the QR code at the
