COURSE DESCRIPTION:
Students are adept at manipulating numbers and equations and understand the general principles at work. Students understand and use factoring of numerators and denominators and properties of exponents. They know the Pythagorean theorem and solve problems in which they compute the length of an unknown side. Students know how to compute the surface area and volume of basic three-dimensional objects and understand how area and volume change with a change in scale. Students make conversions between different units of measurement. They know and use different representations of fractional numbers (fractions, decimals, and percents) and are proficient at changing from one to another. They increase their facility with ratio and propor-tion, compute percents of increase and decrease, and compute simple and compound
interest. They graph linear functions and understand the idea of slope and its relation to ratio.
BOARD ADOPTION DATE: JUNE 20, 2001
AMENDED: SEPTEMBER 18, 2002
Number Sense 1.0
Students compare and order positive and negative fractions, decimals, and mixed numbers. Students solve problems involving fractions, ratios, propor-tions, and percentages:
Number Sense 2.0
Students calculate and solve problems involving addition, subtraction, multiplication, and division.
Algebra and Functions 1.0
Students write verbal expressions and sentences as algebraic expressions and equations; they evaluate algebraic expressions, solve simple linear equations, and graph and interpret their results.
Algebra and Functions 2.0
Students interpret and evaluate expressions involving integer powers and simple roots.
Algebra and Functions 3.0
Students graph and interpret linear and some nonlinear functions.
Algebra and Functions 4.0
Students solve simple linear equations and inequalities over the rational
numbers.
Measurement and Geometry 1.0
Students choose appropriate units of measure and use ratios to convert within and between measurement systems to solve problems.
Measurement and Geometry 2.0
Students compute the perimeter, area, and volume of common geometric objects and use the results to find measures of less common objects. They know how perimeter, area, and volume are affected by changes of scale:
Measurement and Geometry 3.0
Students know the Pythagorean theorem and deepen their understanding of plane and solid geometric shapes by constructing figures that meet given conditions and by identifying attributes of figures.
Statistics, Data Analysis, & Prob. 1.0
Students collect, organize, and represent data sets that have one or more vari-ables and identify relationships among variables within a data set by hand and through the use of an electronic spreadsheet software program.
Mathematical Reasoning 1.0
Students make decisions about how to approach problems.
Mathematical Reasoning 2.0
Students use strategies, skills, and concepts in finding solutions.
Mathematical Reasoning 3.0
Students determine a solution is complete and move beyond a particular problem by generalizing to other situations.
