Course Description

 

Core Standards of the Course

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

Objective 1
Represent rational numbers in a variety of ways.

1. Demonstrate multiple ways to represent whole numbers, decimals, fractions, percents, and integers using models and real-life examples.
   
2. Simplify numerical expressions with whole number exponents using order of operations, and recognize that any positive number to the 0 power is 1.
   
3. Represent numbers greater than one using scientific notation.
   
4. Select the most appropriate form of a rational number for a given context.
   

Objective 2
Compare and order rational numbers, including positive and negative fractions, positive and negative mixed numbers, and positive and negative decimals.

1. Identify, read, and locate rational numbers on a number line.
   
2. Compare pairs of rational numbers in different forms.
   
3. Order rational numbers with and without a number line.
   

Objective 3
Explain relationships and equivalencies among rational numbers.

1. Find equivalent forms for common fractions, decimals, percents, and ratios, including repeating or terminating decimals.
   
2. Predict the effect of operating with fractions, decimals, percents, and integers as an increase or a decrease of the original value.
   
3. Recognize and use the identity properties of addition and multiplication, the multiplicative property of zero, and the commutative and associative properties of addition and multiplication, and the distributive property of multiplication over addition.
   
4. Recognize and use the inverse operations of adding and subtracting a fixed number, multiplying and dividing by a fixed number, and computing squares of whole numbers and taking square roots of perfect squares.
   

Objective 4
Model meanings of ratios and operations with rational numbers.

1. Demonstrate that the fraction a/b represents a divided by b.
   
2. Recognize percents as ratios based on 100 and decimals as ratios based on powers of 10.
   
3. Extend the multiplication of whole numbers to multiplication of fractions using area models, measurement models, and the number line.
   
4. Compare the division of whole numbers to the division of fractions using area or set models, the number line, and missing factors.
   

Objective 5
Solve problems involving rational numbers.

1. Compute fluently using all four operations with integers and positive fractions and decimals.
   
2. Solve problems using factors, multiples, prime factorization, relatively prime numbers, and common divisibility rules.
   
3. Solve application problems involving rational numbers.
   
4. Determine if an answer is reasonable using estimation.
   

Standard 2
Students will use proportional reasoning to solve problems.

Objective 1
Solve problems involving ratios, rates, proportions and percentages.

1. Solve ratio and rate problems using informal methods involving multiplication and division.
   
2. Solve percent problems using ratio and proportion, including problems involving discounts, interest, taxes, tips, and percent increase or decrease.
   
3. Solve problems involving proportions, rates, and measures.
   

Objective 2
Apply the properties of proportionality to different units of measurement.

1. Convert from one unit of measurement to an equivalent unit of measurement in the same system using a given conversion factor.
   
2. Understand that in a proportional relationship, all dimensions change by the same scale factor.
   
3. Create and interpret scale drawings and approximate distance on maps using proportions.
   

Standard 3
Students will develop fluency with the language and operations of algebra to analyze and represent relationships

Objective 1
Evaluate, simplify, and solve algebraic expressions and equations.

1. Write a variable expression to identify pattern relationships, and use those expressions to make predictions.
   
2. Translate verbal expressions into algebraic expressions.
   
3. Simplify and evaluate algebraic expressions.
   
4. Show that performing the same operation on both sides of an equation will produce an equivalent equation.
   
5. Solve single-variable linear equations and inequalities of the form ax + b = c, ax + b < c, or ax + b > c.
   

Objective 2
Represent relationships using graphs, tables, and other models.

1. Identify integer coordinates when given the graph of a point on a rectangular coordinate system.
   
2. Graph ordered pairs of integers on a rectangular coordinate system.
   
3. Model real-world problems using graphs, tables, equations, manipulatives, and pictures.
   

Standard 4
Students will use algebraic, spatial, and logical reasoning to solve geometry and measurement problems.

Objective 1
Draw, label, and describe attributes of geometric shapes to determine geometric relationships.

1. Draw, label, and describe relationships among line segments, rays, lines, parallel lines, and perpendicular lines, including midpoint of a line segment.
   
2. Draw, label, and describe relationships among vertical, adjacent, complementary, and supplementary angles.

1. Estimate metric and customary measures using everyday objects and comparisons.
   
2. Measure length, area, volume, and angles to appropriate levels of precision.
   
3. Calculate the measurement of everyday objects using formulas for perimeters and areas of triangles and quadrilaterals, and circumferences and areas of circles.
   
4. Calculate the measurement of everyday objects using formulas for surface area and volume of prisms and cylinders.
   

Standard 5
Students will understand concepts from probability and statistics and apply statistical methods to solve problems.

Objective 1
Use basic concepts of probability to determine the likelihood of an event and compare the results of various experiments.

1. Write the results of a probability experiment as a fraction, ratio, or decimal, between zero and one, or as a percent between zero and one hundred, inclusive.
   
2. Compare experimental results with theoretical probability.
   
3. Compare individual, small group, and large group results of a probability experiment.
