1. HOMEWORK Due Today: None
2. Cumulative ratio/proportion information Drill
3. Page 6 Problem 1.1 plus modification.

OBJECTIVE: •To explore several ways to make comparisons[1.3.1][1.3.2] •To begin to understand how to determine when comparisons can be made using multiplication or division versus addition or subtraction •To begin to develop ways to use ratios, fractions, rates, and unit rates to answer questions involving proportional reasoning ACTIVITIES/ASSESSMENT: Ration/Proportion Drill Handout; Page 6 Problem 1.1 plus modification. The modification can be comprised of a set of data and having students composing comparisons using ratio, difference, actualnumbers and percent. (similar to the cols wars idea) NOTES: New Text - Comparing and Scaling HOMEWORK: Page 10 1-3
