Nikki's Sesame Street Video Post

Ratio

Two term ratios: compares two quantities measured in the same units
eg: triangles to circles 2:5

Three term ratios: compares three quantities measured in the same units
eg: triangles to circles to squares 1:5:3

Part to part ratio: compares different parts together
eg: triangles: rectangles 3:7

Part to whole ratio: compares one part to the whole group
eg: 1:34

RATE
Rate compares two quantities measured in different units
eg Tina can walk 100 steps/1 minute

Unit rate is when a second term is one
eg Tina walks 200 steps/2minutes

Unit price is a rate used when shopping
eg 0.99 c/ 100 g of rice

Proportional Reasoning
Proportional reasoning is when it says to rates or two ratios are equal
eg 2:4 1:2

  1. Nice post Nikki. You missed one thing in your post which was the original Sesame Street video, add that in. Also try not to use the colour yellow, it's hard to read. Everything else was fine, I have nothing else to say about it.

  2. Good job, Nikki ! I like your video :)
    I like how you made your important words different colors. But next time don't use REALLY bright colors like yellow.
