Section 1
(50 cards)
Area
A model of multiplication that shows each place value product.
Benchmark Fractions
Fractions that are commonly used for estimation.
Associative Property of Multiplication
The product stays the same when the grouping of factors is changed. (a x b) x c= a x (b x c), where a, b, and c stand for any real numbers.
Denomination
The quantity below the line in a fraction. It tells the number of equal parts into which a whole is divided.
Array
An arrangement of objects in equal rows.
Finite Decimal
A decimal that contains a termination number of digits. Also called termination decimal.
Coordinates
An ordered pair of numbers that identify a point on a coordinate plane.
Coordinate System
Also known as a coordinate grid. A 2-dimensional system which the coordinates of a point are its distances from two intersection, usually perpendicular, straight lines called axes.
Compose
To put together, as in numbers or shapes.
Equivalent Fraction
Fractions that have the same value.
Decimal
A number with one or more digits to the right of a decimal point. Decimal is used as another name for decimal fraction.
Factor
An integer that divides evenly into another.
Base of a Solid FIgure
A base of a solid figure is usually thought of as a face upon which it can "sit." Most solid figured have more than one base.
Commutative Property of Multiplication
The produce stays the same when the order of factors is changed. a x b = b x a, where a and b are any real numbers.
Distributive Property
When one of the factors of a product is a sum, multiplying each addend before adding does not change the product.
Data
Information, especially numerical information. Usually organized for analysis.
Customary System
A system of measurement used in the U.S. The system includes units for measuring length, capacity, and weight.
Decimal Point
A dot separation the whole number for the fraction in a decimal notation.
Base of an Exponent
The number that is raised to a power. In 10^4, 10 is the base and 4 is the exponent. 10 is raised to the power of 4.
Commutative Property of Addition
The sum stays the same when the order of addends is changed. a + b = b +a, where a and b are any real numbers.
Estimate
A number close to an exact amount, and estimate tells about how much.
Decompose
To separate into components or basic elements.
Cubic Unit
A unit such as a cubic meter to measure volume or capacity.
Addend
Any number being added.
Brackets
A type of grouping symbol used in pairs that tells what operation to complete first.
Improper Fraction
A fraction where the numerator is greater than or equal to the denominator.
Less than
Less than is used to compare two numbers when the first number is smaller than the second number.
Axis
A reference line from which distances or angles are measured in a coordinate grid. (plural- axes)
Equation
A statement that two mathematical expressions are equal.
Exponent
The number that tells the number of times the base is multiplied by itself.
Braces
Braces can be used to indicate that the objects written between them belong to a set.
Attribute
A characteristic e.g. size, shape, or color.
Intersect
To meet or cross.
Difference
The amount that remains after one quantity is subtracted from another.
Dividend
A quantity to be divided.
Hundredths
In a decimal numeration system, hundredths is the name of the next place to the right of the tenths.
Associative Property of Addition
The sum stays the same when the groupings of addends is changed. (a+b)+c=a+(b+c), where a, b, and c stand for any real numbers.
Area Model
A model of multiplication that shows each place value product.
Hundredth
One of the 100 equal parts of a whole.
Corresponding Terms
Terms that are in the same position in a sequence of numbers.
Greater Than
Greater than is used to compare two numbers when the first number is larger than the second number.
Formula
A general equation or rule. You can use a formula to find volume in a rectangular prism.
Inequality
A mathematical sentence that compares two unequal expressions using one of the symbols <, >. e.g. 26>13; 13<26; 2+4 < 6+3
Evaluate
To find the value of a mathematical expression.
Algorithm
Step-by-step method for computing.
Coordinate Plane
A 2-dimensional system in which the coordinates of a point are its distances from two intersections, usually perpendicular, straight lines called axes.
Expression
A variable or combination of variables, numbers, and symbols that represents a mathematical relationship.
Expanded Form
A way to write numbers that shows the place value of each digit.
Divisor
The quantity bu which another quantity is to be divided.
Centimeter (cm)
A metric unit of length equal to 0.01 of a meter.
Section 2
(50 cards)
Rounding
To strategy to find about how much or how many by expressing a number closest to ten, hundred, thousand, or tenth, hundredth, thousandth, ect.
Sum
The result of addition
Plane
A flat surface that extends infinitely in all directions.
Powers of Ten
Using a base number of 10 with an exponent. Our number system is based on the powers of 10.
Thousandths
Thousandths is the name of the next place to the right of the hundredths in the decimal numeration system.
Millimeter (mm)
A metric unit of length.
Ordered Pairs
A pair of numbers that gives the coordinates of a point on a grid in this order (horizontal, coordinate, vertical coordinate.
Tenths
In the decimal numeration, tenths is the name of the place to the right of the decimal point.
Multiplication Identity Property of 1
Multiplying a number by one gives a product identical to the given number. Also known as Identity Property of Multiplication.
Parentheses
Used in mathematics as grouping symbols for operations. When simplifying an expression, the operations within the parentheses are preformed first.
Minuend
In subtraction, the minuend is the number you subtract from.
Simplify
To express a fraction in simplest form.
Metric System
A system of measurement based on tens. The basic unit of capacity is the liter. The basic unit of mas is the gram.

A geometric figure with 3 dimensions.
Unit Fraction
A fraction with a numerator of 1.
Whole Numbers
Whole numbers are zero and the counting numbers 1, 2, 3, and so on. If a number has a negative sign, a decimal point, or a part that's a fraction, it is not a whole number.
