# Core Connections, Course 3 - Grade 8

• Core Connections, Course 3 is the third of a three-year sequence of courses designed to prepare students for a rigorous college preparatory algebra course. On a daily basis, students in Core Connections, Course 3 use problem-solving strategies, questioning, investigating, analyzing critically, gathering and constructing evidence, and communicating rigorous arguments justifying their thinking. Students learn in collaboration with others while sharing information, expertise, and ideas. The course helps students to develop multiple strategies to solve problems and to recognize the connections between concepts. The lessons in the course meet all of the content standards and embed the “Mathematical Practices” of the Common Core State Standards released in June 2010.

Upon completion of this course, students should be able to:
• Represent a linear function with a graph, table, rule, and context and create any representation when provided one of the others.
• Solve systems of equations by using tables and graphs.
• Symbolically manipulate expressions to solve problems including those with fractional coefficients.
• Solve contextual word problems using multiple strategies, including making tables, looking for patterns, drawing diagrams, and creating a table of guesses to assist with writing and solving a variable equation.
• Describe various geometric transformations on a coordinate grid.
• Represent data using scatterplots and describe associations.
• Collect and analyze data and make predictions based on the trend of the data.
• Compare ratios and calculate unit rates and slope ratios.
• Analyze the slope of a line graphically, numerically, and contextually.
• Recognize and solve problems involving proportional relationships.
• Graph and analyze non-linear functions.
• Recognize and use the properties of similar figures to solve problems.
• Use the Pythagorean Theorem and its converse to solve problems in two and three dimensions.
• Use square roots and cube roots.
• Represent and simplify expressions using positive and negative exponents.
• Represent and compare large and small numbers using standard and scientific notation.
• Perform operations with numbers represented in scientific notation.
• Use the relationships between angles created by parallel lines with transversals and the Triangle Angle Sum Theorem to solve problems.
• Compute the volume of a variety of solid.
