In Topic 3: Proportional Relationships, students will be:

• writing and interpreting ratios involving rational numbers. 

• using various operations to create tables of equivalent ratios.

• using ratio tables to solve ratio problems.

• using ratios and rates to describe the relationship between two quantities.

• finding equivalent ratios and using unit rates to solve multi-step problems.

• finding unit rates with ratios of fractions.

• using unit rates to solve multi-step problems.

• using dimensional analysis to convert one unit of measure to another.

• determining whether quantities are proportional by testing for equivalent ratios.

• using the constant of proportionality to write equations that represent proportional relationships.

• using equations to solve problems involving proportional relationships.

• using a graph to recognize proportionality.

• identifying a constant of proportionality from a graph.

• interpreting a point on a graph of a proportional relationship.

• explaining whether a situation represents a proportional relationship.

• using representations to find entry points into problems.

Note: Students will be allowed to use a calculator and conversion chart on Lesson SC-3.
