# Determine If 2 Ratios Are Equivalent Math Games

In this series of games, your students will learn how to decide whether two quantities are in a proportional relationship. The Determine If 2 Ratios Are Equivalent learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 7.RP.A.2.a as written in the common core national math standards.

## Concepts Covered

Ratios happen when there are two or more quantities related. Ratios can have the same units (ratios) or different units (rates). The term Ratio can be used for same and different units as well. Determine if two quantities are proportional by using or creating a ratio table and seeing if the values are in proportion change in a constant manner. Determine if two quantities are proportional by creating a table and graphing. If the two quantities are proportional their coordinates will fall on a straight line that passes through the origin.

Graph a line showing the relationship of two variables to determine proportionality by determining if the line passes through the origin and has a constant slope. Determine if a relationship is proportional in a table by finding the difference in x values and the difference in y values. If the relationship is proportional then the x and corresponding y values will have the same rate of change.
