Classwork - Tape Diagrams and Equivalent Ratios

Last week we used tape diagrams to learn about equivalent ratios and solve word problems. Tape diagrams are a great way to visualize ratio relationships. Below is an example of how we can use a tape diagram to represent and solve a problem.

Example: The ratio of the number of shoes Mr. E has to the number of sneakers Mr. E has is 5:2

If Mr. E has 25 shoes, how many sneakers does he have?

The five tapes represent the number of shoes Mr. E has. If we divide (25 ÷ 5)  then we know that each tape represents 5 shoes.

Now we can find out the number of sneakers Mr. E has, which is 10. Mr. E has 10 sneakers.

Homework - September 26th - Ratios

Today we learned about ratios in class. Ratios are a comparison between two (or more) quantities. For example, if I wanted to write the ratio of the number of shoes I have to the number of sneakers I have, I would write the ratio 5:2, because I own 5 pairs of shoes and 2 pairs of sneakers. There are two other ways we can represent ratios. We  can also write ratios as a fraction (5/2), or we can just write it out (5 to 2).

We can also represent ratios using a drawing. We call this a Tape Diagram.

Summer School 2016!

Summer school 2016 is here! The students have been learning things they didn't really get throughout the school year, or brushing up on their knowledge of rates. In this video the kids are just taking turns quizzing each other using a book from Pearson on Ratios & Rates.
