## Algebraic Reasoning

Standard 1 Algebraic Reasoning: Patterns and Relationships - The student will use number properties and algebraic reasoning to identify, simplify, and solve simple linear equations and inequalities.
1. Identify, describe, and analyze functional relationships (linear and nonlinear) between two variables (e.g., as the value of x increases on a table, do the values of y increase or decrease, identify a positive rate of change on a graph and compare it to a negative rate of change). (Determining Slope , Independent and Dependent Variables )
2. Write and solve two-step equations with one variable using number sense, the properties of operations, and the properties of equality (e.g., -2x + 4 = -2). (Single Variable Equations 2 , Algebraic Word Problems )
3. Inequalities: Model, write, solve, and graph one-step linear inequalities with one variable. (Single Variable Inequalities , Number Line Inequalities )

## Number Sense and Operations

Standard 2 Number Sense and Operation - The student will use numbers and number relationships to solve a variety of problems.
1. Number Sense
a. Compare and order positive and negative rational numbers. (Compare Mixed Values 2 , Compare Integers )
b. Build and recognize models of perfect squares to find their square roots and estimate the square root of other numbers (e.g., the square root of 12 is between 3 and 4). (Estimating Square Roots , Perfect Squares )
c. Demonstrate the concept of ratio and proportion with models (e.g., similar geometric shapes, scale models). (Basic Fraction Simplification , Fraction Simplification , Proportions 1 , Ratios )
2. Number Operations
a. Solve problems using ratios and proportions. (Area and Volume Conversions , Unit Cost , Proportions 2 , Distance, Rate, and Time )
b. Solve percent application problems (e.g., discounts, tax, finding the missing value of percent/part/whole). (Percentage Change , Purchases At Stores , Restaurant Bills , Commissions , Percent of Quantity , Simple Interest )
c. Simplify numerical expressions with integers, exponents, and parentheses using order of operations. (Using Parentheses , Order Of Operations , Integer Addition , Integer Subtraction , Integer Multiplication , Integer Division , Exponent Basics , Exponent Rules For Fractions )

## Geometry

Standard 3 Geometry - The student will apply the properties and relationships of plane geometry in a variety of contexts.
1. Classify regular and irregular geometric figures including triangles and quadrilaterals according to their sides and angles. (Triangle Types , Quadrilateral Types )
2. Identify and analyze the angle relationships formed by parallel lines cut by a transversal (e.g., alternate interior angles, alternate exterior angles, adjacent, and vertical angles). (Identifying Angles , Angle Measurements , Angle Measurements 2 )
3. Construct geometric figures and identify geometric transformations on the rectangular coordinate plane (e.g., rotations, translations, reflections, magnifications). (Translations and Reflections )

## Measurement

Standard 4 Measurement - The student will use measurement to solve problems in a variety of contexts.
1. Develop and apply the formulas for perimeter and area of triangles and quadrilaterals to solve problems. (Triangle Area , Parallelogram Area , Compare Rectangle Area and Perimeter , Trapezoids )
2. Apply the formula for the circumference and area of a circle to solve problems. (Circle Area , Circle Circumference )
3. Find the area and perimeter of composite figures to solve application problems. (Perimeter and Area of Composite Figures )

## Data Analysis

Standard 5 Data Analysis - The student will use data analysis, probability, and statistics to interpret data in a variety of contexts.
1. Data Analysis: Compare, translate, and interpret between displays of data (e.g., multiple sets of data on the same graph, data from subsets of the same population, combinations of diagrams, tables, charts, and graphs).
2. Probability: Determine the probability of an event involving “or”, “and”, or “not” (e.g., on a spinner with one blue, two red and two yellow sections, what is the probability of getting a red or a yellow?). (Probability , Probability 2 )
3. Central Tendency: Compute the mean, median, mode, and range for data sets and understand how additional data or outliers in a set may affect the measures of central tendency. (Mean, Median, Mode )
