- Summary
- Understand that since a percent increase or decrease is a percent of an original amount, it makes sense to associate the original amount with 100% when solving problems.
- Reason about percentages as rates per 100 to solve percent increase and decrease problems.
- Encounter some situations where it is sensible to express the change in a quantity as a percentage of the starting amount.
- Demonstrating that when I know the new amount and the percentage of increase or decrease, I can find the original amount.
- Demonstrating that I understand that if I know how much a quantity has grown, then the original amount represents 100%.
- Demonstrating that I can use a double number line diagram to help me solve percent increase and decrease problems.
