Data and Graphs
1. coordinate grid: a grid used to show ordered pairs.
2. data: pieces of collected information.
3. line graph: a graph that connects points to show how data
changes over time.
4. plot: to locate and mark a point named by an ordered pair on a
grid.
5. ordered pair: a pair of numbers that names a point on a
coordinate grid.
6. scale: numbers that show the units used on graph.
7. trend: a pattern in the data on a line graph, shown by an increase
or decrease.
8. x-axis: a horizontal line that includes both positive and negative
numbers.
9. y-axis: a vertical line that includes both positive and negative
numbers.
10. line plot: a display of responses along a number line with X’s
recorded above the responses to indicate the number of times a
response occurred.
11. data: collected information
12. integers: the whole numbers and their opposites; 0 is its own
opposite.
13. coordinates: the two numbers in an ordered pair.
14. point: an exact location in space.
15. line: a straight path of points that goes on forever in two
directions.
16. origin: the point where the two axes of a coordinate plane
intersect. The origin is represented by the ordered pair (0,0).
17. coordinate plane: a coordinate grid that extends to include both
positive and negative numbers.
18. x-coordinate: the first number in an ordered pair, which names the
distance to the right or left from the origin along the x-axis.
19. y-coordinate: the second number in an ordered pair, which names
the distance up or down from the origin along the y-axis.
Place Value and Number Sense
1. place: the place where the number is located. Example the 3 is in the
hundreds place in 314.
2. value: how much the number is worth. Example the value of the 3 in
324 is 300.
3. decimal: a number with one or more places to the right of a decimal
point.
4. decimal point: a dot used to separate dollars from cents or ones
from tenths in a number.
5. thousandths: one out of 1,000 equal parts of a whole.
6. estimate: to give an approximate value rather than an exact answer.
7. order of operation: the order in which operations are done in
calculations. Work inside parentheses is done first. Next, terms with
exponents are evaluated. Then multiplication and division are done in
order from left to right, and finally addition and subtraction are done
in order from left to right.
8. parentheses: Used in mathematics as grouping symbols for
operations. When simplifying an expression, the operations within the
parentheses are performed first.
9. bracket: A type of grouping symbol used in pairs that tells what
operation to complete first. Example [ (2 x 20) + 6].
10. number expression: an expression that contains numbers and at
least one operation. A number expression is also called a numerical
expression.
11. exponents: a number that tells how many times the base is used as a
factor. Example: 103 = 10 x 10 x 10; the exponent is 3 and the base is 10.
12. algebraic expression: a mathematical phrase involving a variable or
variables, numbers, and operations. Example: x-3
13. prime factorization: the process of writing a whole number as a
product of its prime factors.
Fractions and Decimals
1. decimal point: a dot used to separate dollars from cents or ones
from tenths in a number.
2. equivalent fractions: fractions that name the same region, part
of a set, or part of a segment.
3. fraction: a fraction is a symbol, such as 2/3, used to name a part
of a whole, a part of a set, a location on a number line, or a
division of whole numbers.
4. improper fraction: a fraction in which the numerator is greater
than or equal to the denominator.
5. mixed number: a number that has a whole number and a fraction.
6. numerator: the number above the fraction bar in a fraction.
7. simplest form: a fraction in which the numerator and denominator
have no common factors other than 1.
8. fraction: a symbol, such as 2/3, 5/1, or 8/5, used to describe one
or more parts of a whole that is divided into equal parts. A fraction
can name a part of a whole, a part of a set, a location on number
line, or a division of whole numbers.
9. denominator: the number below the fraction bar in a fraction.
10. benchmark fraction: common fractions used for estimating, such
as ¼, 1/3, ½.2/3, and ¾.
11. greatest common factor (GCF): the greatest number that is a
factor of two or more given numbers.
12. least common denominator (LCD): the least common multiple of
the denominators of two or more fractions.
13. least common multiple (LCM): the least number that is a common
multiple of two or more numbers.
14. common denominator: a number that is the denominator of two or
more fractions.
