Chapter/Concept Chapter 13 Bar Graphs & Line Plots Vocabulary Term Definition/Meaning ExampleVertical A bar graph showing bars that are up and
down. Vertical means up and down direction.
Horizontal A bar graph showing bars that side to side.Horizontal means side to side direction.
Scale Scale shows the value of the bar. The scale could be vertical or horizontal depending on the type of bar graph.
x-axis (horizontal) The Horizontal line showing either bars or a scale depending on the type of graph. A horizontal bar graph has a scale on its x-axis and bars on its y-axis. x-axis
y-axis (vertical) The Vertical line showing either bars or scale depending on the type of graph. A vertical bar graph a scale on its y-axis and bars on its y-axis
Chapter/Concept Chapter 13 Bar Graphs & Line Plots Vocabulary Term Definition/Meaning Exampleorigin The intersection where the x-axis and y-
axis meet. This is the “zero” mark on the scale.
survey To gather information about a specific subject and collect it into a graph to display data.
Tally chart/Frequency Table
A table used to collect information in which each item is counted using tally marks and/ornumbers.
Bar Graph A bar graph is a chart that uses bars to show comparisons between different categories of data.
range The range is the smallest to largest values on the graph scale. They are based on your data. Ex: 0-25
Range = 0-25Chapter/Concept Chapters 6,7, & 8 Multiplication & Division Vocabulary Term Definition/Meaning ExampleMultiply To find a product using multiplication 3 x 2 = 6
Factor x Factor = Product
Product The answer to a multiplication problem 4 x 4 = 1616 is the product
Factor The numbers being multiplied 5 x 2 = 105 and 2 are factors
Multiple ~The order of numbers when counting by a given number.~A number that can be divided by another number without a remainder.
ex: 2, 4, 6, 8, 10, 128 is a multiple of 2ex: 5, 10, 15, 20, 2520 is a multiple of 5
Array An arrangement of rows and columns used in multiplication to demonstrate repeated addition
3 x 5 = 153 rows of 5 = 15
Chapter/Concept Chapters 6,7, & 8 Multiplication & Division Vocabulary Term Definition/Meaning ExampleEqual groups Having the same number of items in
each group
3 groups of 4 or 3 x 4Identity Property of One
The product of 1 and any number is that number
ex: 1 x 2 = 2 4 x 1 = 4 1 x 49 = 49
Identity Property The product of 0 and any number is ex: 3 x 0 = 0
of Zero always 0 0 x 6 = 0 0 x 35 = 0
Associative Property of Multiplication
When three or more numbers are multiplied, the product is always the same regardless of the grouping
ex: (3 x 2) x 4 = 24 2 x (3 x 4) = 24
Commutative Property of Multiplication
When two products are multiplied, the product is always the same regardless of the order of the factors
ex: 4 x 2 = 2 x 4 5 x 6 = 6 x 5
Vocabulary Term Definition/Meaning ExampleArea The number of square units needed to
cover the surface of a figure without any overlap.
A = L x W(Area = Length x Width)
Square Units Units of area, such as square centimeter, square inch, square foot, square meter, etc.Square centimeter square inch square foot square meter cm in ft m
Perimeter The distance around a figure that can be measured in linear units.
P = L + W + L + W(Perimeter = length + width + length +
width)
Vocabulary Term Definition/Meaning ExamplePlane Figures Flat figures with length and width.
They may be open or closed.
Polygon A closed plane figure formed by three or more line segments.
Vertex Where two line segments come together. Sometimes forming a corner or a point. The plural of vertex is vertices.
Quadrilaterals Any closed figure made up of line segments having four sides.
Parallel Parallel lines are straight lines that always stay the same distance from each other and never meet:
Vocabulary Term Definition/Meaning ExampleRight Angle An angle of 90°, as in a corner of a square
or at the intersection of two perpendicular straight lines.
Acute Angle An acute angle is an angle smaller than a right angle. The range of an acute angle is between 0 and 89 degrees.
Obtuse Angle The obtuse angle is more than 90° and less than 180°.
Straight Angle An angle of 180°. Has the appearance of a line, but has a point and is made up of two line segments or rays.
Perpendicular Two lines which meet at a right angle.
Vocabulary Term Definition/Meaning ExamplePoint A point is shown by a dot. A point can
be on a line, ray, or vertex
Line Segment The part of a line that connects two points. It has two definite end points. Adding the word "segment" is important, because a line normally extends in both directions without end.
Line A line is defined as a line of points that extends infinitely (forever) in two directions
Ray A ray is a line with a single endpoint that extends infinitely (forever) in one direction.
Vocabulary Term Definition/Meaning ExampleWhole A figure made of equal parts with nothing
removed. All parts intact.
Part A part of a whole. One or more pieces removed or shaded.
Numerator The top portion of the fraction which represents any number of parts of a whole.

Equal Parts Fractions are formed when we have a WHOLE that is divided into so many EQUAL parts.
Mixed Number A whole number combined with a fraction Ex: 1 ¾ , 5 ½, 7 ¼
Improper Fraction A fraction with a numerator larger then it’s denominator
Ex:
