Grades 6-8
The **sixth grade** standards:


 * Ratios and Proportional Relationships - Understand ratio concepts and use ratio reasoning to solve problems.
 * The Number System - Extend previous understanding of fractions including multiplying and dividing fractions, compute fluently with multi-digit numbers and find common factors and multiples.
 * Expressions and Equations - Reason about and solve one-variable equations and inequalities.
 * Geometry - Solve real-world and mathematical problems involving area, surface area, and volume.
 * Statistics and Probability - Develop understanding of statistical variability.

The **seventh grade** standards:
 * Ratios and Proportional Relationships - Analyze proportional relationships and use them to solve real-world and mathematical problems.
 * The Number System - extend previous knowledge using the four operations with fractions and the ability to divide and multiply rational numbers.
 * Expressions and Equations - Use properties of operations to generate equivalent expressions.
 * Geometry - Draw, construct and describe geometrical figures and describe the relationships between them.
 * Statistics and Probability - Ability to use random samplings and make inferences about populations, investigate chance processes and develop, use, and evaluate probability models.

The **eighth grade** standards:
 * The Number System - Know that there are numbers that are not rational, and approximate them by rational numbers.
 * Expressions and Equations - Work with radicals and integer exponents, understand the connections between proportional relationships, lines, and linear equations.
 * Functions - Define, evaluate, and compare functions.
 * Geometry - Understand congruence and similarity using physical models, transparencies, or geometry; understand and apply the Pythagorean Theorem.
