Do Now!

Talk to the person next to you about a time that you raised money for a cause.

How much money did you raise?

How much more or less did you raise than the person sitting next to you?

Could you write a comparative sentence about the money you raised and the money raised by the person next to you.

Could you compare the amounts using a ratio or a fraction?

6th grade = $300

8th grade = $150

300 - 150 = $150

1/3 of the 7th grade total = $150

2/3 of the 7th grade total = $300

$300 ÷ 2 = $150

The 6th grade goal is double the 8th goal.

For every $1 the eighth grade plans to raise, the seventh grade plans to raise $3.
