Course Description

 

Core Standards of the Course

Standard 1
Students will expand number sense to understand, perform operations, and solve problems with real numbers.

Objective 1
Represent real numbers as points on the number line and distinguish rational numbers from irrational numbers.

1. Define a rational number as a point on the number line that can be expressed as the ratio of two integers, and points that cannot be so expressed as irrational.
   
2. Classify numbers as rational or irrational, knowing that rational numbers can be expressed as terminating or repeating decimals and irrational numbers can be expressed as non-terminating, non-repeating decimals.
   
3. Classify pi and square roots of non-perfect square numbers as irrational.
   
4. Place rational and irrational numbers on a number line between two integers.
   

Objective 2
Compute fluently and make reasonable estimates with rational and irrational numbers.

1. Simplify, add, subtract, multiply, and divide expressions with square roots.
   
2. Evaluate and simplify numerical expressions containing rational numbers and square roots using the order of operations.
   
3. Compute solutions to problems, represent answers in exact form, and determine the reasonableness of answers.
   
4. Calculate the measures of the sides of a right triangle using the Pythagorean Theorem.
   

Standard 2
Students will extend concepts of proportion to represent and analyze linear relations.

Objective 1
Represent and analyze the slope of a line.

1. Identify the slope of a line when given points, a graph, or an equation.
   
2. Identify horizontal and vertical lines given the equations or slopes.
   
3. Determine the effect of changes in slope or y-intercept in y = mx + b .
   
4. Determine and explain the meaning of slopes and intercepts using real-world examples.
   

Objective 2
Model and interpret problems having a constant rate of change using linear functions.

1. Write algebraic expressions or equations to generalize visual patterns, numerical patterns, relations, data sets, or scatter plots.
   
2. Represent linear equations in slope-intercept form, y = mx + b, and standard form, Ax+ By =C.
   
3. Distinguish between linear and non-linear functions by examining a table, equation, or graph.
   
4. Interpret the slope of a linear function as a rate of change in real-world situations.
   

Objective 3
Represent and analyze linear relationships using algebraic equations, expressions, and graphs.

1. Write the equation of a line when given two points or the slope and a point on the line.
   
2. Approximate the equation of a line given the graph of a line.
   
3. Identify the x- and y-intercepts from an equation or graph of a line or a table of values.
   
4. Graph linear relations and inequalities by plotting points, by finding x- and y-intercepts, or by using the slope and any point on the line.
   

Standard 3

1. Collect, record, organize, and display a set of data with at least two variables.
   
2. Determine whether the relationship between two variables is approximately linear or non-linear by examination of a scatter plot.
   
3. Characterize the relationship between two linear related variables as having positive, negative, or approximately zero correlation.
   

Objective 2

2. Interpret the slope and y-intercept of a line through data.
   
3. Predict y-values for given x-values when appropriate using a line fitted to bivariate numerical data.
