Shane's Sesame Street Video Post
Part 1:
Ratio
two-term ratio- compares two quantities (things) measured in the same units.
three-term ratio- compares three quantities measured in the same units.
part to part ratio- compares different parts of a group to each other.
part to whole ratio- compares one part of a group to the whole group.
Example: apples to bananas, 7:20, red squares to total squares, 6:12
Raterate- compares two quantities in different units.
unit rate- a rate in which the second term is one.
unit price- a unit rate used when shopping.
Example: a person's heart can beat 64 beats/minute or a car can move 20 km/hr.
Proportion
proportion- a relationship that says that two ratios or two rates are equal.
Example: you can use proportion to find out what a dozen erasers cost if three erasers cost $0.75. 2/3 = 6/9

Two Term Ratios
compares two quantities measured in the same units
ex. A:B, 9:18, 18 to 9

Proportion
- A relationship that says two ratios or two rates are equal
- it can be written in fraction form
ex. use it to find cost of 15 donuts if 5 cost $0.10
5 / $0.10 = 15 / $x ; x = $o.30 ( multiply 5 by 3 and $o.10 by 3 )
John's Sesame Street Video Post
Two-Term Ratio:
-Compares different parts of a group to each other.
-Compares two quantities measured in the same units.
Ex. A:B, 4:5, 5 to 4

-A relationship that says that two ratio or two rates are equal
Ex. use it to find 15 chickens if 5 costs $0.10

Rate
Compares two quantities measured in different units
Unit Rate
A rate in which the second term is one
Unit Price
A unit rate used when shopping
Example: I eat 2 cookies in 2 minutes, that means I eat 1 cookie per minute.
1 cookie/min
Ratio
Two Term Ratios
Compares two quantities measured in the same units
Example: I eat 2 cookies and there are 4 in the jar. That makes it 2:4
Proportional Reasoning
A relationship that says that two ratios or two rates are equal.
Example: If I eat 1 cookie in 1 minute, then that means I eat 8 cookies in 8 minutes.

Three Term Ratios
~ Compares three quantities measured in the same units
ex. A : B : C, 5 : 23 : 9, 5 to 23 to 9
Rates
~ Compares two quantities measured in different units
Unit Rate
~ A rate in which the second term is one
Unit Price
~ A unit rate used when shopping
ex. Car traveling 3km/hr, $1.00 / gram

Part one:
The original video is Banana sign, we changed our video allot so it is not exactly like the original, we didn't even use sign language in it, so we used the sesame street video as our inspiration. What happens in the video is that Samara is trying to tell Telly she wants a Banana in sign language, but Telly doesn't understand her until the end of the video.
