Worksheet Chapter 6: College Prep Algebra
In this algebra worksheet, students perform a variety of operations. They factor polynomials, solve algebraic equations, identify the GCF, and solve real life word problems. Twelve of these 100 problems are real life word problems.
Curated OER
Prime and Composite Numbers
Fifth graders investigate the concepts of composite and prime numbers. They factor different numbers and determine the number of factors for each. Based upon this information the number is declared prime or composite.
Curated OER
Arrays And Factors
Students participate in a lesson that is concerned with the concepts of arrays and factors. They use a Hershey bar and divide it into segments in order to simulate the arrays. Then students construct other arrays from the leftover pieces.
Curated OER
Exploring Multiplication Functions
Fourth graders investigate the terms "factor" and "product." In this mathematics lesson, 4th graders practice solving problems to find the products and factors present in different algebraic expressions.
