Algebra 1 Teacher’s Edition (2nd ed.) presents algebra concepts in a logical order. The text develops an understanding of algebra by justifying methods and by explaining how to solve problems. It introduces graphing, solving systems of equations, operations with polynomials and radicals, factoring polynomials, solving rational equations, and graphing quadratic functions. Biographical sketches of mathematicians are included, as well as features on probability and statistics, Algebra Around Us, and Algebra and Scripture. The Teacher's Edition includes reduced pages of the student text with notes and answers (including solutions), sections with common student errors, and one-on-one activities.
