equivalent ratios
Instructions
Play through this interactive game to learn about Represent Proportions As Equations. 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.
Represent proportional relationships by equations in the form of y = cx where c is the constant of proportionality.
When setting up the proportion the units must be consistent (if the units are cm as the numerator of one ratio then it must be cm as the units for the numerator on the corresponding ratio).
Forming an equation is done by cross-multiplying two rations ( 4/5 = 80/x to 80*5 to 4x=400).
Using cross-multiplication of two ratios to show equivalent ratios will yield the equation as t = pn.
Discussion Questions
Before the Game
How do you set up a proportion? What are different ways or strategies to solve proportions? What is an equation? Can a proportion be used to solve equations? What is the Cartesian plane?
After the Game
What is direct proportionality? What did you notice about the graphs made? What are the two equations we can use to help us solve proportional situations? What are some strategies to reading graphs?
