Common Core Standards:
*Students will have a calculator available for PARCC assessments
*Absolute Value: The distance of a number from zero on a number line; shown by ∣ ∣.
Base: When a number is raised to a power, the number that is used as a factor is the base.
Coefficient: The number that is multiplied by the variable in an algebraic expression.
Constant: A value that does not change.
Cubed: Raising a number to the third power
*Decimal Expansion: a fraction written in base-10
Equivalent: equal or same
Exponent: The number that indicates how many times the base is used as a factor.
*Exponential Notation: A number written with a base and an exponent.
Inequality: A mathematical sentence that shows the relationship between quantities that are not equivalent.
*Inverse Operation: Operations that undo each other: addition and subtraction, or multiplication and division.
*Irrational Numbers: numbers that cannot be expressed as a ratio of two integers or as a repeating or terminating decimal.
*Linear Equation: An equation whose solutions form a straight line on a coordinate plane.
*Magnitude: The size of a mathematical object, a property by which the object can be compared as larger or smaller than other objects of the same kind. An object's magnitude is the displayed result of an ordering (or ranking) of the class of objects to which it belongs.
One Solution: A value or values that make an equation true.
Perfect Square: A square of a whole number.
Power: A number produced by raising a base to an exponent.
*Properties of Integer Exponents:
Proportional Relationships: A relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
Radical: The symbol √ used to represent the non-negative square root of a number.
Rational Number: repeating or terminating decimals; any number that can be expressed as a ratio of two integers.
*Real Number System: The field of all rational and irrational numbers
Roots: The root of a number x is another number, which when multiplied by itself a given number of times, equals x.
Scientific Notation: A method of writing very large or very small numbers by using powers of 10.
Square Root: A number that is multiplied by itself to form a product is called a square root of that product.
*Symbol Notation: letters or symbolic expressions that are used as stand-ins for unspecified numeric quantities (i.e. an - both a and n are letters representing unspecified quantities).
