A number greater than 1 that has only two factors: 1 and itself (like 7 or 13).
Prime Number
This term describes two or more fractions that name the same amount, like 1/2 and 2/4
equivalent fractions
This term describes the amount of space inside a 2D shape, measured in square units.
area
These are the numbers you multiply together to get a product.
factors
In the problem 20 divided by 5 = 4, the number 20 (the number being divided) is called this
dividend
In the equation n + 5 = 12, the letter n represents an unknown value and is called this.
variable
This is the top number of a fraction, which represents how many parts of the whole are being considered
numerator
This type of graph uses bars to show and compare data
bar graph
This property states that you can multiply numbers in any order and the product stays the same (4 times 5 = 5 times 4)
This is the answer to a division problem
quotient
This is a sequence of numbers or objects that follows a specific rule
pattern
This is the distance all the way around the outside of a 2D shape
perimeter
This is a graph that uses marks (usually Xs) above a number line to show how often data occurs.
line plot
This is the name of the value of the digit to the left of the hundreds place
thousands
This is the answer to an addition problem
sum
The product of a number and any whole number
(2- 2,4,6,8,10...)
multiple
This type of angle measures exactly 90° and forms a perfect "L" shape
right angle
This is the answer to a multiplication problem.
product
When you change a number to the nearest ten, hundred, or thousand to make it easier to work with, you are doing this.
rounding
This is the answer to a subtraction problem
difference
In a fraction, this is the bottom number that tells how many equal parts make up the whole
denominator
These are lines that stay the same distance apart and will never cross or touch
parallel lines
This is the number that remains after one whole number is divided by another
remainder
This is what you do when you determine about how much
estimate
These are lines that cross each other at exactly a 90° angle, forming a "plus" sign
perpendicular lines
