Eighth Grade Algebra I

Instructor: Patty Armstrong

Curriculum Map, Class Page

In Algebra I, students examine how the properties of real numbers, symbols, variables, expressions, equations, and graphs have enabled us to advance in the use of mathematical applications to get where we are today. They complete application problems where they consider change over time.  The students analyze graphs where the horizontal axis is a unit of time.  They use these graphs to compare when different events occur in relation to one another.

Students learn how algebraic knowledge, which includes definitions, formulas, equations, inequalities, exponents, and functions, is useful in the everyday lives of people as they make decisions. They apply this knowledge as they analyze data about how they cost of education relates to the value of the education and they determine how to invest for college. They also examine life expectancy, both in the past and in the future.

In the third trimester, students investigate the algebraic analysis of quadratic equations, polynomials, and radicals and learn how this analysis helps people solve problems and make plans for the future. They analyze financial information and compare different investment strategies. In their final project, they model the population growth of various United States cities and use their models to predict future population. The students see how town planners use population models to make strategic decisions and plans for the future.

Students consider the following questions:

• How do the properties of real numbers and graphing techniques enable us to see where we have been?
• How is algebraic knowledge useful in helping people use data analysis to make everyday decisions?
• How does algebraic analysis of quadratic equations, polynomials, and radicals help people to solve problems and make plans for the future?
