Identify Proportional Relationships (Tables) Worksheet

7 problems

If all the ratios of the variable are equivalent, they are meant to have a proportional relationship. Moreover, in a proportional relationship, one variable is always a constant value times the other variable. This constant value is known as “constant of proportionality”. For instance, y = kx where ‘k’ is the constant of proportionality. This is also known as the unit rate.

Teaching Identifying Proportional Relationships Easily 

 

  • We can easily tell if a table shows a proportional relationship or not. 
  • Firstly, calculate the ratio for each pair of values. 
  • Secondly, determine whether the ratios are equivalent. 
  • If all the ratios of the variable are equivalent, they are meant to have a proportional relationship.
