Oklahoma Standards - Grade 8 Math
The state of Oklahoma has prescribed that students of Grade 8 Math master certain topics. The topics are listed below. Each of these topics/strands are covered in TenMarks, helping students refresh their knowledge, as well as learn as they practice - resulting in mastery.
|
Standard 1: The student will graph and solve linear equations and inequalities in problem-solving situations.
|
|
1.1.a Model, write, and solve multi-step linear equations with one variable using a variety of methods to solve application problems.
|
|
1.1.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.
|
|
1.1.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).
|
|
1.1.d Apply appropriate formulas to solve problems (e.g., d=rt, I=prt).
|
|
1.2 Model, write, solve, and graph one- and two-step linear inequalities with one variable.
|
|
Standard 2: The student will use numbers and number relationships to solve problems.
|
|
2.1 Represent and interpret large numbers and numbers less than one in exponential and scientific notation.
|
|
2.2.a Use the rules of exponents, including integer exponents, to solve problems (e.g., 7? ? 7? = 7 to the 5th power, 3 to the -10th ? 3 to the 8th power = 3-?).
|
|
2.2.b Solve problems using scientific notation.
|
|
2.2.c Simplify numerical expressions with rational numbers, exponents, and parentheses using order of operations.
|
|
Standard 3: The student will use geometric properties to solve problems in a variety of contexts.
|
|
3.1 Construct models, sketch (from different perspectives), and classify solid figures such as rectangular solids, prisms, cones, cylinders, pyramids, and combined forms.
|
|
3.2 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.
|
|
Standard 4: The student will use measurement to solve problems in a variety of contexts.
|
|
4.1 Develop and apply formulas to find the surface area and volume of rectangular prisms, triangular prisms, and cylinders (in terms of pi).
|
|
4.2 Apply knowledge of ratio and proportion to solve relationships between similar geometric figures.
|
|
4.3 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).
|
|
5.1 Select and apply appropriate formats (e.g., line plots, bar graphs, stem-and-leaf plots, scatter plots, histograms, circle graphs) to display collected data.
|
|
Standard 5: The student will use data analysis and statistics to interpret data in a variety of contexts.
|
|
5.1 Select, analyze and apply data displays in appropriate formats to draw conclusions and solve problems.
|
|
5.2 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?).
|
|
5.3 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.
