Real & Complex Number Systems

Ratios and Proportional Relationships

Analyze proportional relationships and use them to solve real-world and mathematical problems: Understand ratio concepts and use ratio reasoning to solve problems; use ratio and rate reasoning to solve real-world and mathematical problems; recognize and represent proportional relationships between quantities; use proportional relationships to solve multistep ratio and percent problems.

Perform Operations

Apply and extend previous understandings of operations: Divide fractions by fractions; compute fluently with multi-digit numbers and find common factors and multiples; add, subtract, multiply, and divide rational numbers; perform arithmetic operations with complex numbers; solve real-world and mathematical problems involving the four operations with rational numbers; reason quantitatively and use units to solve problems.

Extend and Use Properties

Apply and extend previous understandings of numbers to the system of rational numbers: Know that there are numbers that are not rational, and approximate them by rational numbers; extend the properties of exponents to rational exponents; use properties of rational and irrational numbers; solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane.
