IDStandardStudyPug Topic

8.NS.A.1Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
- Rational vs. Irrational numbers
- Understanding the number systems
8.NS.A.2Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2).

- Estimating square roots
8.EE.A.1Know and apply the properties of integer exponents to generate equivalent numerical expressions.
- Product rule of exponents
- Quotient rule of exponents

- Solving systems of linear equations by graphing
- Determining number of solutions to linear equations
- Solving systems of linear equations by elimination

- Identifying functions
- Relationship between two variables
8.F.A.2Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).
- Function notation
8.F.B.4Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
- Applications of linear relations
8.F.B.5Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
- Graphing linear functions using table of values
8.G.A.1Verify experimentally the properties of rotations, reflections, and translations.
- Tessellations using translations and reflections
- Line symmetry
8.G.A.2Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

- Applications of pythagorean theorem
- Distance formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
8.G.C.9Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.
- Word problems relating volume of prisms and cylinders
- Surface area and volume of cones
- Surface area and volume of spheres

8.SP.A.1Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.
- Reading linear relation graphs
- Box-and-whisker plots and scatter plots
8.SP.A.2Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.
