Indiana Standards - Grade 8 Math
The state of Indiana 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 8.1: Number Sense and Computation
|
|
8.1.1 Interpret calculator or computer displays of numbers given in scientific notation and read, write, compare and solve problems using decimals in scientific notation.
|
|
8.1.2 Recognize positive integer powers as repeated multiplication and negative integer powers as repeated division or multiplication by the multiplicative inverse.
|
|
8.1.3 Use the laws of exponents for integer exponents and evaluate expressions with negative integer exponents.
|
|
8.1.4 Identify, compare and order irrational numbers.
|
|
8.1.5 Calculate square roots of perfect squares, estimate square roots of numbers less than 1,000, and use the inverse relationship between squares and square roots.
|
|
8.1.6 Solve percent, ratio and proportion problems.
|
|
Standard 8.2: Algebra and Functions
|
|
8.2.1 Write and solve linear equations and inequalities, interpret the solution or solutions in their context, and verify the reasonableness of the results.
|
|
8.2.2 Solve equations and formulas for a specified variable.
|
|
8.2.3 Simplify algebraic expressions involving powers.
|
|
8.2.4 Identify and graph linear functions and identify lines with positive and negative slope.
|
|
8.2.5 Find the slope of a linear function given the equation and write the equation of a line given the slope and any point on the line.
|
|
8.2.6 Translate among tables, equations, verbal expressions and graphs of linear functions and recognize that in (y = mx + b) that m is the rate of change and b is the vertical intercept of the graph.
|
|
8.2.7 Identify functions as linear or nonlinear and contrast their characteristics from tables, graphs and equations.
|
|
8.2.8 Use linear functions and linear equations to represent, analyze and solve problems.
|
|
Standard 8.3: Geometry and Measurement
|
|
8.3.1 Perform basic compass and straight edge constructions: angle and segment bisectors, copies of segments and angles, and perpendicular segments. Describe and justify the constructions.
|
|
8.3.2 Identify, define, and describe properties of three-dimensional geometric objects, describe how two or more figures intersect in a plane or in space, and visualize or describe the cross section of a solid.
|
|
8.3.3 Explain why the Pythagorean Theorem is valid using a variety of methods and use the Pythagorean Theorem and its converse to calculate lengths of line segments
|
|
8.3.4 Solve simple problems involving rates and other derived measurements, including problems involving speed, uniform speed, average speed and density, by applying the concept of proportionality to measurement in different contexts. Express measurements in a given unit or in terms of other units of the same type.
|
|
8.3.5 Use scale factors to find the area and volume of similar figures.
|
|
8.3.6 Find and use the surface area and volume of cones, spheres and pyramids.
|
|
8.3.7 Estimate and compute the area of irregular two-dimensional shapes and the volume of irregular three-dimensional objects by breaking them down into more basic geometric objects.
|
|
8.3.8 Solve problems involving conversions within the same measurement system and estimate the measure of an object in one system given the measure of that object in another system and the approximate conversion factor.
|
|
Standard 8.4: Data Analysis and Probability
|
|
* 8.4.1 Identify claims based on statistical data and, in simple cases, evaluate the reasonableness of the claims. Design a study to investigate the claims
|
|
* 8.4.2 Identify different methods of selecting samples, analyzing the strengths and weaknesses of each method and the possible bias in a sample or display.
|
|
* 8.4.3 Use mean, median, mode, upper and lower quartiles and range to compare data sets. Organize and display data to highlight important features such as the range and how the data is spread around a central value. Investigate what happens to the display when some of the data values are changed.
|
|
* 8.4.4 Analyze, interpret and display data in box-and-whisker plots.
|
|
* 8.4.5 Display two-variable data in scatter plots and describe how the data points are distributed. If the pattern appears to be linear, draw a line that appears to best fit the data and write the equation of that line.
|
|
* 8.4.6 Describe and apply the addition rule for probabilities for simple events that are mutually exclusive and for simple events that are not.
|
|
* 8.4.7 Compute probabilities of events from simple experiments with equally probable outcomes, using such methods as organized list, tree diagrams and area models.
