6.RP.1, 6.RP.2, 6.RP.3 and 6.RP.4- Ratios and Proportional Reasoning
conclude
(v.) to finish; to bring something to an end; to decide after careful thought To bring to an end
discrete data
Data that cannot be broken into smaller parts. Ex: 5 cats(can't have 1/2 a cat)
ratio
3 different ways to express ratios
ratio box
3 parts of ratio box: Part Part Whole number Use the box to turn initial ratio into actual numbers
conversion
A conversion is the change between two units (usually units of measurement).
reflection
A mirror image of a point over a reflection line
ratio
A multiplicative relationship between two numbers that does not change.
coordinate plane
A plane formed by the intersection of two perpendicular number lines.
percent
A rate per 100. A special ratio that compares a number to 100 using the symbol %
unit ratio/rate
A ratio in which one of the quantities is 1.
multiplicative relationship
A relationship between two numbers formed by multiplying or dividing.
table
A tool to organize numerical data. A table listing pairs of numbers that form equivalent ratios.
graph
A tool to show the relationship between two values
part-to-part
A type of ratio comparing a part of one group to part of another group. (Adjective) compare one part to another
part-to-whole
A type of ratio comparing a part of one to group to the whole group. (Adjective) compare one part to the entire quantity
unit ratios
A unit rate where the denominator is one unit.
continous data
Data that represents things that can be broken into smaller parts. Ex: 3.5 ft. (can be divided into smaller parts)
equality
Having the same value
identify
Provide an answer from a number of possibilities. Find; point out
equivalent Ratio
Ratios that express the same relationship between two quantities.
x-axis
The horizontal number line on a coordinate plane
origin
The intersection of the x- and y- axes
y-coordinate
The number of vertical units a point is from the origin
y-axis
The vertical number line on a coordinate plane
coordinate
Two numbers that identify the location of a point
ordered pair
Two numbers that identify the location of a point
proportional
When two ratios are equivalent
equation
a mathematical sentence in which two expressions are set equal to each other
conversion factor
a ratio of equivalent measurements used to convert a quantity from one unit to another A ratio of equivalent measurements
proportional reasoning
ability to recognize when two ratios are equivalent Using the concept of proportions when analyzing and solving a mathematical situation
Rate
d/t (distance)/(time) A ratio that compares two quantities measured in different units
approximate
estimate or guess Not exact, but close enough to be reasonably correct
add, plus, +
means to add things together
scale factor
shows the relative multiplicative change in the magnitude of the quantities form one ratio to another.
x-coordinate
the number of horizontal units a point is from the origin
assume
to take for granted or without proof take to be the case or to be true
