North Dakota Standards - Grade 8 Math
The state of North Dakota 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.
|
Number, Number Relationships, and Number Systems
|
|
* 8.1.1 Identify subsets of the real number system; i.e., natural and whole numbers, integers, rational and irrational numbers
|
|
* 8.1.2 Solve real-world problems involving ration, proportion, and percent
|
|
* 8.1.3 Identify perfect squares 1 to 144 and approximate square roots
|
|
* 8.1.4 Represent large and small numbers using scientific notation
|
|
Operations and Their Properties
|
|
* 8.1.5 Apply operation properties to simplify computations and solve problems; i.e., commutative, associative, and distributive
|
|
* 8.1.6 Apply the order of operations to simplify numeric expressions and solve problems
|
|
Computational Fluency and Estimation
|
|
* 8.1.7 Add, subtract, multiply, and divide integers
|
|
* 8.1.8 Select and use a computational technique (e.g., mental calculation, paper-and-pencil, technology) to solve problems
|
|
* 8.1.9 Determine when an estimate is sufficient and an exact answer is needed in problem situations
|
|
Two- and Three-Dimensional Shapes, Geometric Properties and Relationships
|
|
* 8.2.1 Use nets to represent the relationships between two- and three-dimensional figures
|
|
* 8.2.2 Classify quadrilaterals based on side lengths, angle measures, and sets of parallel sides
|
|
* 8.2.3 Identify the angles formed and the relationships between the angles when parallel lines are intersected by a transversal
|
|
* 8.2.4 Apply the Pythagorean Theorem to problems involving right triangles
|
|
* 8.2.5 Represent shapes using coordinate geometry
|
|
Transformation and Symmetry
|
|
* 8.2.6 Draw the results of a combination of transformations in the coordinate plane; i.e., reflections, rotations, and translations
|
|
* 8.2.7 Use scale, proportion, and congruency to solve problems involving similar figures
|
|
Visualization, Spatial Reasoning, and Geometric Modeling
|
|
* 8.2.8 Use two-dimensional representations of three-dimensional objects to visualize and solve problems; e.g., those involving surface area and volume
|
|
Data Collection, Display, and Interpretation
|
|
* 8.3.1 Formulate a question and select a random or representative sample
|
|
* 8.3.2 Collect, organize, and display data using scatter and stem-and-leaf plot
|
|
* 8.3.3 Determine possible outcomes using organized lists, tree diagrams, Venn diagrams, factorials, and the basic counting principle
|
|
* 8.3.4 Distinguish between experimental and theoretical probability; i.e., the results of an experiment may not match the theoretical probability
|
|
* 8.3.5 Calculate and compare the measures of central tendency (i.e., mean, median, mode) and spread (i.e., range)
|
|
* 8.3.6 Identify an outlier within a set of data and discuss its effects on the measures of central tendency and spread
|
|
Predictions, Data Analysis and Inferences
|
|
* 8.3.7 Make inferences based on analysis of data and interpretation of graphs
|
|
Measurable Attributes, Measurement Systems and Units
|
|
* 8.4.1 Select an appropriate degree of precision when using measurements for calculations
|
|
* 8.4.2 Compare unit measurements between systems, e.g., a yard is almost a meter
|
|
Measurement Tools, Techniques and Formulas
|
|
* 8.4.3 Use formulas to determine the surface area and volume of right cones and spheres
|
|
Patterns, Relations, and Functions
|
|
* 8.5.1 Extend numerical patterns; e.g., Pascal's triangle and the Fibonacci sequence
|
|
Numeric and Algebraic Representations
|
|
* 8.5.2 Use variables, expressions and equations to represent problem situations
|
|
* 8.5.3 Apply the order of operations and the commutative, associative, and distributive properties to simplify algebraic expressions
|
|
* 8.5.4 Apply inverse operations and the properties of equality to solve multi-step equations and inequalities in one variable
|
|
* 8.5.5 Write multi-step equations and inequalities to represent problem situations
|
|
* 8.5.6 Solve problems involving rates; i.e., speed equals distance divided by time (miles per hour)
