Dividing by (x – a) and (x + a)
Patterns in math emerge from seemingly random places. Learners explore the patterns for factoring the sum and differences of perfect roots. Analyzing these patterns helps young mathematicians develop the polynomial identities.

The Division of Polynomials
Build a true understanding of division of polynomials. Learners use their knowledge of multiplying polynomials to create an algorithm to divide polynomials. The area model of multiplication becomes the reverse tabular method of division.
Curated OER
Pascal's Triangle
Learners explore the concept of Pascal's Triangle. In this Pascal's Triangle lesson, students use an applet called 'Coloring Multiples' to explore Pascal's Triangle. Learners develop patterns starting with various numbers in Pascal's...

Which Bag is Which?
Young scholars explore number sense by completing a statistical analysis game in class. In this data graphing lesson, students utilize visual references such as colored cubes and tiles to map out the results of an experiment outcome such...
Curated OER
Modular Arithmetic Station
Eighth graders find ways to use math everyday. In this algebra lesson, 8th graders model equation and problem solving as they multiply and divide numbers. They split up in to groups as they perform hands on operations.

Polynomial Divisions
Students factor polynomials and use long division t solve problems. In this algebra lesson, students find the zeros of polynomials by synthetic and long division. They perform operation using complex numbers.
