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

- Exponent rules
- Order of operations with exponents
8.EE.A.2Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.
- Cubic and cube roots

8.EE.B.6Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.
- Slope intercept form: y = mx + b

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

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.

- 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

- 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.
