Curated OER
Difference of Squares
Learners analyze arithmetic statements. In this difference of squares lesson, students explore patterns and factor the difference of two squares. They compare quantities with integers. Learners model and solve equations.
Curated OER
Zeros of a Quadratic Function
Factor quadratic equations by teaching your students how to identify the zeros of the quadratic function. They use the TI to see where the graph will intercept the coordinate plane.

A Polynomial Quilt
Tenth graders create polynomial quilts. In this polynomials lesson, 10th graders use concrete models, such as construction paper, to create various shapes described. Students use the FOIL method to multiply terms and to get a square...
Curated OER
Factors and Multiples
Sixth graders need to see the relevance in the mathematics they learn. This lesson builds on the concepts of least common multiple and greatest common factor. The lesson presents real-world problem situations for students to solve.
Curated OER
Pascal's Triangle
Middle schoolers study Pascal's triangle. They construct their own version of Pascal's triangle, and relate some of the uses for it. While working through this process, students practice their integer multiplication and division skills.
Curated OER
Clock Arithmetic and Cryptography
Students perform basic operations in modular (clock) arithmetic. Students encode and decode messages using shift and affine ciphers. Students apply their multiplication, division, addition, and subtraction skills.
Curated OER
Patterns in Pascal's Triangle
Young scholars examine the patterns that exist in Pascal's Triangle. They explore multiples and factors. Sudents use an applet to create and color the multiples in Pascal's Triangle.
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.
Curated OER
Mixed Expressions and Complex Fractions
Students are introduced to mixed expressions and complex fractions. They work through several problems with the instructor and then complete a worksheet.
