Justin's Sesame Street Video Post

Our Math group was Justin and Nicholas


2 term ratio: Compares 2 quantities measured in the same units.
Example: 5:9

3 term ratio: Compares 3 quantities measured in the same units.
Example: 3:5:9

Part to part ratio: Compares different parts of the group to each other.
Example: 7:5

Part to whole ratio: Compares 1 part of the group to the whole group.
Example: 9:30

Rate:Compares two quantities measured in different units.
Example: 72 beats/ min

Unit rate: A rate in which the send term is 1.
Example: 20 km an hour

Unit price: A unit used when shopping, often shown per 100g or per 100ml, makes it easier for shoppers to compare costs of similar items.
Example: $2.19/100g

Proportional Reasoning:A relationship that says two ratios or two rates are equal, can be written in fraction form.
Example: 10 erasers cost $2, how much will 20 erasers cost?

Here is a link to the video that we chose to do, its about the letter R.

Here is our remake of the video


  1. Great job, Justin ! Your video was really well done, but short. Your blog is getting better. I really like hwo you changed the font. Keep it up !

  2. Good job! Nice video but it was only 31 seconds. You changed the font to show the important words. You could of even used colour. Good job!

  3. Nice Post you got there Justin :),You explained rates,ratio,and proportion real well!But,like me,our video was a lil' short..Maybe,we can make it a lil' longer next time :/

  4. Nice job Justin. Your video was kept simple which was nice. It was good that you included all the definitions but maybe you could have added examples and pictures. Overall, good job!

  5. Good job Justin! You're video got right to the point and so did your blog. It was very neat but next time, try to add some examples, pictures, and colour.

  6. Great Job Justin i know we should of made the video longer.But i like how you wrote what rate,Proportional Reasoning,Ratio:
    really neatly keep up the good work justin
