Four Key Focus Areas
Systems of Linear Equations
Expressions and Equations
Identifying and Using Functions
Classifying Two and Three Dimensional Figures
Concepts to Master
Working with Roots and Exponents
Know and solve perfect square and cube roots
Know what a negative exponent represents.
Be able to write exponents as fractions
Rules of Exponents
Be able to multiply exponents with the same bases by adding the exponents
Be able to raise powers to powers by multiplying the exponents
Use same icon style to keep consistency.
Scientific Notation
Write numbers in scientific notation
Translate numbers written in scientific notation to standard notation
Use rules of exponents to add, subtract, multiply and divide numbers written in scientific notation
Slope-Intercept Form
Transfer understanding of unit rates to slopes
Write equations in the form of y=mx+b
Use similar triangles to demonstrate that the slope of a line remains consistent throughout the line
Linear Equations
Solve linear equations that lead to one solution, infinite solutions, or no solutions
Understand the graph of a line represents solutions to a linear equation
Write and solve linear equations with two variables
Systems of Linear Equations
Understand the solution to a system of linear equations is their intersection on a graph
Analyze and solve systems of linear equations
Solve systems of linear equations by graphing and substitution
Functions
Know that a function has one output for every input
Represent the graph of a function as a set of coordinates representing inputs and outputs
Compare functions using graphs, tables, and equations
Evaluating Functions
Know that equations written in the form y=mx+b will result in a straight line
Give examples of functions that are not linear
Know if the graphs of functions are increasing, decreasing, linear, or non-linear
Bivariate Data
Analyze scatter plots to determine if there is a negative association, positive association or no association
Write an equation in slope intercept form to represent a line of best fit for the data
Make a prediction about the data using the line of best fit
Understand Congruence of Transformations
Demonstrate and explain why shapes remain congruent during rotations, translations, and reflections
Demonstrate and explain why shapes remain similar when dilated
Pythagorean Theorem
Explain the pythagorean theorem and its converse
Use the pythagorean theorem to find any unknown side length of a right triangle
Use the pythagorean theorem to find the distance between two coordinates on a coordinate plane
Volume
Find the volume of cones, cylinders, and spheres
Know the formulas for volume of cones, cylinders, and spheres
Understand rules of parallel lines cut by a transversal
