###
Graphing Proportional Relationships

Given a proportional relationship, students will be able to graph a set of data from the relationship and interpret the unit rate as the slope of the line.

###
Analyzing Scatterplots

Given a set of data, the student will be able to generate a scatterplot, determine whether the data are linear or non-linear, describe an association between the two variables, and use a trend line to make predictions for data with a linear association.

###
Writing Geometric Relationships

Given information in a geometric context, students will be able to use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.

###
Solutions of Simultaneous Equations

Given a graph of two simultaneous equations, students will be able to interpret the intersection of the graphs as the solution to the two equations.

###
Comparing and Explaining Transformations

Given rotations, reflections, translations, and dilations, students will be able to develop algebraic representations for rotations, and generalize and then compare and contrast the properties of congruence transformations and non-congruence transformations.

###
Mean Absolute Deviation

Given a set of data with no more than 10 data points, students will be able to determine and use the mean absolute deviation to describe the spread of the data.

###
Evaluating Solutions for Reasonableness

Given problem situations, the student will determine if the solutions are reasonable.

###
Predicting, Finding, and Justifying Solutions to Problems

Given application problems, the student will use appropriate tables, graphs, and algebraic equations to find and justify solutions to problems.

This resource presents supporting information of the mathematics TEKS for Kindergarten through Grade 12.

###
Multiple Representations: Tables to Equations and Graphs

Learn about differences between multiple representations in 8th grade and in Algebra I, including tables, equations, and graphs.

###
Estimating Measurements and Using Formulas: Surface Area

Given application problems involving lateral or total surface area the student will estimate measurements and solve the problems.

###
Determining the Effects of Proportional Change on Area

Given pictorial representations and problem situations involving area, the student will describe the effects on area when dimensions are changed proportionally.

###
Determining the Effects of Proportional Change on Perimeter

Given pictorial representations and problem situations involving perimeter, the student will describe the effects on perimeter when dimensions are changed proportionally.

###
Generating Different Representations of Relationships

Given problems that include data, the student will generate different representations, such as a table, graph, equation, or verbal description.

###
Predicting, Finding, and Justifying Data from a Graph

Given data in the form of a graph, the student will use the graph to interpret solutions to problems.

###
Approximating the Value of Irrational Numbers

Given problem situations that include pictorial representations of irrational numbers, the student will find the approximate value of the irrational numbers.
