Common+Core+Grade+7

= = __**Common Core Grade 7**__ //The following information is derived from the Ohio Department of Education, Mathematics Common Core Standards (2011).//

The concentration in 7th math grade focuses on four areas: (**Domains** -> Clusters)
 * 1) **Understanding and Application of proportions.**
 * Percentage, Discounts, interest, taxes, tips, % increase or decrease
 * Similar objects (similar triangles, polygons, etc...)
 * Understanding/Graphing proportional and inverse relationships, slope
 * 1) **Rational Numbers, Expressions and Linear equations.**
 * Fractions/Decimals/Percents are representations of rational numbers
 * Extend addition, subtraction, multiplication and division to all rational numbers
 * Negative numbers (real world quantities, i.e. amount owed, temperatures below zero, etc...)
 * Use of rational numbers and expressions to formulate equations in one variable.
 * 1) **Problem Solving w/Scale drawings, 2-D, and 3-D shapes to analyze area, surface area and volume.**
 * 2) **Data analysis (inferences about populations based on samples).**

= __**Example**__ = Domain: Expressions and Equations - 7.EE Cluster: Use properties of operations to generate equivalent expressions. Standard: 1) Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
