double number line

Definition: A double number line diagrams is a pair of parallel number lines with the numbers 0 aligned. Each number line is marked in equal increments and numbered. The tick marks are aligned, but the numbers on the two lines are often different. A pair of aligned numbers on the diagram represents a ratio that is equivalent to every other pair of aligned numbers on the diagram. Example: A - is useful for some problems using smaller numbers. An example of a problem that can be solved with a - could be: To make hot cocoa you need 1 cups of milk and 6 teaspoons of chocolate. How much cocoa could you make with 5 cups of milk?

The tick marks are aligned, but the numbers on the two lines are often different. A pair of aligned numbers on the diagram represents a ratio that is equivalent to every other pair of aligned numbers on the diagram. Example: Our double number line represents speed to distance. On the double number line you can either start with your unit rate and find equivalent ratios, or have multiple equivelent ratios, and try to find the original unit rate. Our model shows the distance which is 10 miles and speed which is 60 mph.

Example: We used the __________________ to represent the ratio of cat to dogs.

ratio

Definition: A ratio associates two or more quantities. Ratios can be described in words such as "3 to 2" and "3 for every 2" and "3 our of every 5" and "3 parts to 2 parts". We write ratios with symbols like this 3:2/ Example: An example is 2 bananas to 1 watermelon. A ratio is when you compare 2 quantities of something.

table

Definition: A table is a way to organize information. Each rectangle in the table is called a cell. Each horizontal set of entries is called a row, and each vertical set of entries is called a column. The first row in a table often contains headers to explain what information is in each column Example: An example of a _____ is apples to lemons like in the one that we have shown.

With 22 hours to 24 miles.

tape diagram

Definition: A tape diagram can be used to represent a ratio between two quantities measured in the same units. It is composed of one or more rectangles that are partitioned into equal parts. Each part represents a value. It can be any value, as long as the same value is used throughout. Example: A ____ _____ is just one way to show the ratio 6:2.

Meters per second

Definition: A unit to measure speed that tells you how many meters an object travels in one second. Example: An example is a race where you use meters per second to see who had the fastest time and who won the race.

Meters per second

Definition: A unit to measure speed that tells you how many meters an object travels in one second. Example: The car is moving 300__________.

Meters per second

Definition: A unit to measure speed that tells you how many meters an object travels in one second. Example: The car went three _____ ___ ______.

same rate

Definition: In two situations involving ratios of the same two quantities, if the ratio of the quantities in one situation is equivalent to the ratio of the quantities in the other situation then we say the two situations involve the same rate. Example: An example of this is 2 dollars for 1 toy car and 2 dollars for 1 banana. This means that their rates are the same.

same rate

Definition: In two situations involving ratios of the same two quantities, if the ratio of the quantities in one situation is equivalent to the ratio of the quantities in the other situation then we say the two situations involve the same rate. Example: The red and blue truck went at the same rate.

same rate

Definition: In two situations involving ratios of the same two quantities, if the ratio of the quantities in one situation is equivalent to the ratio of the quantities in the other situation then we say the two situations involve the same rate. Example: The same rate in Brady's ratios is 2:4 and 4:8,because they both go up by 2 and 4 every time

unit price

Definition: The unit price is the cost for one item or one unit of measure. Example: An example of unit price is with one tomato. The tomato is the original cost for one tomato. In our example our tomato is 0.69 cents.

unit price

Definition: The unit price is the cost for one item or one unit of measure. Example: The ------ ----- for one toy robot is $5.00.

unit price

Definition: The unit price is the cost for one item or one unit of measure. Example: The _________ per apple is 70 cents.

unit price

Definition: The unit price is the cost for one item or one unit of measure. Example: The __________ for 1 pumpkin is $9.99.

equivalent ratios

Definition: Two ratios a:b and c:d are equivalent ratios if there is a number s that you can multiply both a and b by c and d (respectively). In other words, a*s=c and b*s=d. Example: 2:4 and 1:2 are____ ____.

equivalent ratios

Definition: Two ratios a:b and c:d are equivalent ratios if there is a number s that you can multiply both a and b by c and d (respectively). In other words, a*s=c and b*s=d. Example: There are 2 apples for every 4 Oranges. There were also 4 apples to 8 oranges. These are .

equivalent ratios

Definition: Two ratios a:b and c:d are equivalent ratios if there is a number s that you can multiply both a and b by c and d (respectively). In other words, a*s=c and b*s=d. Example: We know that ______ can be divided or multiplied to get the same integers as the 1st and 2nd number in that ratio EX: 5:3 The recipe for a almer palmer is 5 cups of lemonade to 3 cups of sweet tea, this can be multiplied by 2 on each number to get 10:6, or it can be multiplied by the numbers going up from 1. So 1,2,3,4,5, and so on to make a larger batch of Almer Palmer

per

The word per means "for each".
