Instructions
Play through this interactive game to learn about Determine If 2 Ratios Are Equivalent. Suitable for Grade 6, Grade 7, Grade 8.
Main Concepts
Ratios can have the same units (ratios) or different units (rates). The term Ratio can be used for same and different units as well.
Ratios happen when there are two or more quantities related.
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 (The vertical change and corresponding horizontal change is constant no matter where the measurement is determined).
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.
Discussion Questions
Before the Game
What is a ratio? How can we compare two ratios to tell if they are equivalent? How can you use ratios to compare quantities on a table or graph? How can we tell if those ratios on the table or graph are proportional?
After the Game
How did the graph in the game help you to see if two values were proportional? What strategies did you use to find the missing numbers in the tables? What makes a proportional relationship? Define what the constant of proportionality is and how it can found on a table or graph?
