Ninth graders investigate multiplication of binomials and factoring of trinomials.  In this Algebra I lesson plan, 9th graders compare and contrast expansion and factoring using algebra tiles and a TI-89.

Students factor trinomials using algebra tiles and blocks. In this algebra lesson, students complete a trinomials station activity. They work backwords to find their answers and discuss their steps in a group.

Students factor trinomials. In this algebra lesson, students use special patterns and formulas to factor. They utilize algebra tiles as a hands-on method for gaining practice with trinomials.

This comprehensive unit investigates transformations of quadratics, having learners follow "Optima" through the development and growth of her quilting business. Deftly weaving the story into the mathematical mechanics, the unit gives...

Students create factor trees.  For this prime and composite lesson, students model fractions using tiles.  They create factor trees and identify prime and composite numbers.  Students use grid paper and tiles to model...

Put out by Texas Instruments, this lesson involves learners in an activity focused on adding polynomials, solving equations, factoring trinomials, and expanding binomials. A TI-89 calculator is needed to complete this lesson.

What does completing the square have to do with circles? Math pupils use completing the square and other algebraic techniques to rewrite equations of circles in center-radius form. They then analyze equations of the form x^2 + y^2 + Ax +...

Ninth graders factor equations and find prime numbers. In this algebra lesson, 9th graders find the factors and prime factors of a number using multiples and relatively prime numbers.

Students factor trinomials and other quadratic functions. For this algebra lesson, students solve trinomials containing negative and positive coefficients. They factor quadratics of difference squares as well as regular polynomials.

Students simplify equations and expressions. In this algebra lesson, students add, subtract, multiply and divide as they solve expressions. They relate factoring to solving polynomials.
