ratio_and_rate_notes.docx |

In class today we created a web of all the information we remembered from previous grades. The above notes were also handed out to help student connect the dots between the new vocabulary and previously learned concepts.

The following are the highlights:

- there are 3 main ways to write a ratio ( with "to", a colon ":', or as a fraction)

- there are 2 types of ratios

1. Part to part (comparing two different pieces from same group)

2. Part to whole (comparing a piece to the total in the group)

- ratios have to have something in common (same units)

- Unit rate and unit price are for (per) one item. (unit = uni = ONE)

- rates have different units, so both must be mentioned. Ex. beats per hour, dollars per day, etc.

Once again we will be working in groups for this unit.

(Red = independent, Blue = semi-independent, Green = with teacher)

The following are the textbook questions suggested for this unit:
