I.
Course Description:
The eighth-grade standards contain both content that reviews or extends concepts and skills learned in
previous grades and new content that prepares students for more abstract concepts in Algebra and Geometry.
Students will gain proficiency in computation with rational numbers (positive and negative fractions, positive and
negative decimals, whole numbers, and integers) and use proportions to solve a variety of problems. New concepts
include solving two-step equations and inequalities, graphing linear equations, visualizing three-dimensional shapes
represented in two-dimensional drawings, applying transformations to geometric shapes in the coordinate plane, and
using matrices to organize and interpret data. Students will verify and apply the Pythagorean Theorem and represent
relations and functions using tables, graphs, and rules.

Calculators will be used to assist in problem solving and verifying solutions.
The student will also need:
• 3-ring binder for storing class notes and other handouts
• Loose leaf paper
• Pencils
III.
Course Objectives:
Students will:
• Simplify numerical expressions involving positive exponents, using rational numbers, order of
operations, and properties of operations with real numbers.
• Compare and order decimals, fractions, and percents, and numbers written in scientific notation.
• Describe orally and in writing the relationships between the subsets of the real number system.
• Solve practical problems involving rational numbers, percents, ratios, and proportions.
• Determine the percent of increase or decrease for a given situation.
• Apply the order of operations to evaluate algebraic expressions for given replacement values of
the variables.
• Determine whether a given number is a perfect square.
• Find the two consecutive whole numbers between which a square root lies.
• Verify by measuring and describe the relationship among vertical angles, adjacent angles,
supplementary angles, and complementary angles.
• Measure angles of less than 360 degrees.
• Investigate and solve practical problems involving volume and surface area of prisms, cylinders,
cones, and pyramids.
• Describe how changing one measured attribute of a figure affects the volume and surface area.
• Apply transformations to plane figures and identify applications of transformations.
• Construct a three-dimensional model, given the top or bottom , side, and front views.
• Verify and apply the Pythagorean Theorem.
• Solve practical area and perimeter problems involving composite plane figures.
• Determine the probability of independent and dependent events with and without replacement.
• Make comparisons, predictions, and inferences, using information described in graphs.
• Construct and analyze scatterplots.
• Make connections between any two representations (tables, graphs, words, and rules) of a given
relationship.
• Solve multistep linear equations in one variable with the variable on one and two sides of the
equation.
