Oklahoma Math Standards - 8th GradeMathScore aligns to the Oklahoma Math Standards for 8th Grade. The standards appear below along with the MathScore topics that match. If you click on a topic name, you will see sample problems at varying degrees of difficulty that MathScore generated. When students use our program, the difficulty of the problems will automatically adapt based on individual performance, resulting in not only true differentiated instruction, but a challenging game-like experience.
Algebraic ReasoningStandard 1 Algebraic Reasoning: Patterns and Relationships - The student will graph and solve linear equations and inequalities in problem solving situations.
a. Model, write, and solve multi-step linear equations with one variable using a variety of methods to solve application problems. (Linear Equations , Single Variable Equations 2 , Single Variable Equations 3 , Algebraic Word Problems )
b. Graph and interpret the solution to one- and two-step linear equations on a number line with one variable and on a coordinate plane with two variables. (Determining Slope )
c. Predict the effect on the graph of a linear equation when the slope or y-intercept changes (e.g., make predictions from graphs, identify the slope or y-intercept in the equation y = mx + b and relate to a graph). (Graphs to Linear Equations )
d. Apply appropriate formulas to solve problems (e.g., d=rt, I=prt). (Simple Interest , Compound Interest , Distance, Rate, and Time )
2. Inequalities: Model, write, solve, and graph one- and two-step linear inequalities with one variable. (Single Variable Inequalities , Number Line Inequalities )
Number Sense and OperationsStandard 2 Number Sense and Operation - The student will use numbers and number relationships to solve a variety of problems.
1. Number Sense: Represent and interpret large numbers and numbers less than one in exponential and scientific notation. (Scientific Notation )
2. Number Operations
a. Use the rules of exponents, including integer exponents, to solve problems (e.g., 72 · 73= 75 3-10· 38 = 3-2). (Exponents Of Fractional Bases , Negative Exponents Of Fractional Bases , Multiplying and Dividing Exponent Expressions , Exponent Rules For Fractions )
b. Solve problems using scientific notation. (Scientific Notation 2 )
c. Simplify numerical expressions with rational numbers, exponents, and parentheses using order of operations. (Using Parentheses , Order Of Operations , Exponents Of Fractional Bases , Negative Exponents Of Fractional Bases , Exponent Rules For Fractions )
GeometryStandard 3 Geometry - The student will use geometric properties to solve problems in a variety of contexts.
1. Construct models, sketch (from different perspectives), and classify solid figures such as rectangular solids, prisms, cones, cylinders, pyramids, and combined forms.
2. Develop the Pythagorean Theorem and apply the formula to find the length of line segments, the shortest distance between two points on a graph, and the length of an unknown side of a right triangle. (Pythagorean Theorem , Line Segments )
MeasurementStandard 4 Measurement - The student will use measurement to solve problems in a variety of contexts.
1. Develop and apply formulas to find the surface area and volume of rectangular prisms, triangular prisms, and cylinders (in terms of pi). (Rectangular Solids , Triangular Prisms , Cylinders )
2. Apply knowledge of ratio and proportion to solve relationships between similar geometric figures. (Area And Volume Proportions , Proportions 2 )
3. Find the area of a “region of a region” for simple composite figures and the area of cross sections of regular geometric solids (e.g., area of a rectangular picture frame). (Irregular Shape Areas )
Data AnalysisStandard 5 Data Analysis - The student will use data analysis, probability, and statistics to interpret data in a variety of contexts.
1. Data Analysis: Select, analyze and apply data displays in appropriate formats to draw conclusions and solve problems.
2. Probability: Determine how samples are chosen (random, limited, biased) to draw and support conclusions about generalizing a sample to a population (e.g., is the average height of a men’s college basketball team a good representative sample for height predictions?).
3. Central Tendency: Find the measures of central tendency (mean, median, mode, and range) of a set of data and understand why a specific measure provides the most useful information in a given context. (Mean, Median, Mode )
