An EXPRESSION is any number, variable, or combination of numbers and variables. Expressions include operations but do not include an equal sign. Examples are 4 + 5, 8, and 3 * a

An EQUATION is a combination of expressions that include an equal sign. The left side of an equation must balance with the right side of the equation. Examples are 4 + 4 = 8, 5 - 2 = 3 * 1, and 7 = 7.

A VARIABLE is a letter used in place of an unknown number.
A VARIABLE is a letter used in place of an unknown number.
An example is 5 + n = 11, so n = 6.
An example is 5 + n = 11, so n = 6.
INVERSE OPERATIONS are operations that "undo" each other.
INVERSE OPERATIONS are operations that "undo" each other.
Addition and Subtraction are inverse operations, and Multiplication and Division are inverse operations which means they "undo" each other.

Examples are 5 + 3 = 8, so 8 - 3 = 5, and 5 X 2 = 10, so 10 / 2 = 5.
Examples are 5 + 3 = 8, so 8 - 3 = 5, and 5 X 2 = 10, so 10 / 2 = 5.

In Fourth Grade, students also learn about Factors & Multiples.
FACTORS are the numbers you multiply together to get another number. For example, 2 x 3 = 6... 2 and 3 are factors of 6. Factors are finite, which means each number has a specific number of factors.

MULTIPLES are your skip counting numbers. For example, 6, 12, 18, and 24 are the first 4 multiples of 6. Multiples are infinite, which means they go on and on forever.

In Fourth Grade, students learn about Prime & Composite Numbers.
PRIME NUMBERS are numbers that are greater than one and have only 2 factors (1 x itself). For example, 11 is prime, because 1 x 11 is 11 and that's it. 11 has 2 factors or 1 factor pair. 2 is the only even number that is prime.

COMPOSITE NUMBERS are numbers that are greater than one and have more than 2 factors. For example, 12 is composite, because 1 x 12, 2 x 6, and 3 x 4 all equal 12. 12 has 6 factors or 3 factor pairs. All even numbers, except 2, are composite.
