| the number of square units needed to cover a surface. l x w = formula for a rectangle | area |
| of equal measure; having the same size and same shape | congruent |
| polygon with ten sides and ten angles | decagon |
| the part of a fraction below the bar that tells how many equal parts there are | denominator |
| answer to subtraction | difference |
| a triangle with three equal sides and 3 acute 60 degree angles | equilateral triangle |
| polygon with seven sides and seven angles | heptagon |
| polygon with six sides and six angles | hexagon |
| opposite operations, or ones that undo each other such as addition and subtraction or multiplication and division | inverse operations |
| a triangle with two congruent sides, with all acute, one obtuse or right angle | isosceles triangle |
| a pattern where the x-coordinate is multiplied by the same number each time or y = ax | multiplicative pattern |
| polygon with nine sides and nine angles | nonagon |
| the part of a fraction above the bar that tells the number of fractional pieces being used | numerator |

| polygon with eight sides and eight angles | octagon |
| a pair of numbers used to locate a point on a coordinate plane (x,y) | ordered pair |
| lines in the same plane that do not cross each other; they stay the same distance apart | parallel lines |
| a quadrilateral where opposite sides are parallel and congruent | parallelogram |
| distance around a figure | perimeter |
| polygon with five sides and five angles | pentagon |
| lines that cross and form a right (90 degree) angle | perpendicular lines |
| a closed plane figure formed by three or more line segments | polygon |
| the total when two or more factors are multiplied | product |
| polygon with four sides and four angles | quadrilateral |
| a quadrilateral that is a parallelogram and has four right angles | rectangle |
| polygon with all sides and all angles congruent | regular polygon |
| a quadrilateral that is a parallelogram and has four congruent sides | rhombus |
| a triangle with one right (90 degree) angle | right triangle |
| a triangle with no congruent sides, with all acute, one obtuse, or one right angle | scalene triangle |
| a quadrilateral that is a parallelogram and has four right angles (rectangle) and four congruent sides (rhombus) | square |
| answer to addition | sum |
| a quadrilateral that only has one pair of parallel sides | trapezoid |
| polygon with three sides and three angles | triangle |
| the first number in an ordered pair; it tells how far left or right to move from (0,0) | x-coordinate |
| the second number in an ordered pair; it tells how far up or down to move from (0,0) | y-coordinate |
| base | the surface a solid object stands on |
| composite number | a whole number with more than 2 factors |
| cube | 3D figure that is a special rectangular prism with 6 square faces |
| dimension | a measure of length in one direction |
| divisible | when a number can be divided by another with a whole number quotient and no remainder |
| factor | a number multiplied by another number to find a product |
| prime number | a whole number greater than 1 with exactly two factors |
| quotient | the size of each group or the number of groups when the dividend is divided by the divisor |
| rectangular prism | 3D figure that has 6 rectangular faces, 12 edges, and 8 vertices |
| volume | the measure of the space occupied by matter; l x w x h = rectangular prism |
| whole numbers | the set of counting numbers and zero ( 0, 1, 2, 3, ...) |
| base area | designated as a capital B in formulas and refers to the area of one of the bases in a solid |
| equation | a mathematical sentence that shows two things are equal |
| numerical expression | a mathematical phrase that uses only numbers and operation signs |
| order of operations | the rules that say which calculation comes first when simplifying an expression (PEMDAS) |
| associative property | different combinations do not affect sums 1 +(2 + 3) = (1 + 2) + 3, or products 2 x (3 x 4) = (2 x 3) x 4; it does not apply to subtraction or division |
| axes | the horizontal, (x), and vertical (y), lines that act as reference points when plotting points on a coordinate grid |
| commutative property | order does not affect sums 2 + 3 = 3 + 2, or products 4 x 5 = 5 x 4; it does not apply to subtraction or division |
| coordinate grid | a two-dimensional plane on which to plot points, lines, and curves |
| distributive property | in multiplication a factor can be broken into pieces; 4 x 56 - 4 x 50 + 4 x 6 |
| expanded form | the representation of a number as a sum of place values like 57 = 5 x 10 + 7 x 1 |
| hundredths | second decimal place to the right |
| origin | the starting point where the axes of a coordinate plane intersect; (0,0) |
| tenths | first decimal place to the right |
| thousandths | third decimal place to the right |
| x - axis | the horizontal (left to right) line on a coordinate plane that runs through zero |
| y - axis | the vertical (up and down) line on a coordinate plane that runs through zero |
| improper fraction | a fraction where the numerator is larger than the denominator |
| LCD | the least common multiple of the denominators of two or more fractions |
| mixed number | a whole number and a fraction together |
| simplest form | a fraction where the numerator and denominator do not have any common factors except 1 |
| unit fraction | a fraction whose numerator is 1 |
