Building Toward:
NC.7.RP.1
NC.7.RP.2
Building On:
NC.6.RP.3
When there is a constant rate, I can identify the two quantities that are in a proportional relationship.
I can use a table with 2 rows and 2 columns to find an unknown value in a proportional relationship.
Lesson 4:
Addressing:
NC.7.RP.2
Building Toward:
NC.7.RP.3
Building On:
NC.6.EE.3
NC.6.RP.3
NC.7.RP.1
I can use the distributive property to rewrite an expression like (x + ½ x) as (1 + ½ )x.
I understand that “half as much again” and “multiply by 3/2” mean the same thing.
Lesson 5:
I can write fractions as decimals.
I can use the distributive property to rewrite an equation like x+0.5x=1.5x.
I understand that “half as much again” and “multiply by 1.5” mean the same thing.
Lesson 6:
Addressing:
NC.7.RP.3
Building Toward:
NC.7.RP.3
Building On:
NC.6.RP.3
I can draw a tape diagram that represents a percent increase or decrease.
When I know a starting amount and the percent increase or decrease, I can find the new amount.
Lesson 7:
When I know the new amount and the percentage of increase or decrease, I can find the original amount.
I understand that if I know how much a quantity has grown, then the original amount represents 100%.
I can use a double number line diagram to help me solve percent increase and decrease problems.
