Curated OER
Factoring Trinomials
Students factor trinomials and other quadratic functions. In this algebra activity, students solve trinomials containing negative and positive coefficients. They factor quadratics of difference squares as well as regular polynomials.
Curated OER
Solving Algebraic Expressions
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.
Curated OER
Factoring Quadratic Trinomials
In this factoring trinomials activity, 9th graders solve and complete 36 various types of problems. First, they write each trinomial in factored form. Then, students write all of the factor pairs of the third term and circle the pair...
Curated OER
Factors, Divisibility, and Relatively Prime
Seventh graders explore the concept of divisibility. In this divisibility lesson, 7th graders use divisibility rules to find factors of numbers. Students create foldables to illustrate divisibility rules.
Curated OER
Prime and Composite Numbers with use of manipulatives (Elementary, Mathematics)
Students learn what prime and composite numbers are. They learn how to identify them by working in a group and demonstrating an understanding of one work problem with 100% accuracy using the manipulatives provided.
