Grade 8 - Functions - MCC8.F.1 & MCC8.F.2

Unit Overview for Teachers

  • In grade 6, students plotted points in all four quadrants of the coordinate plane. They also represented and analyzed quantitative relationships between dependent and independent variables.
  • In Grade 7, students decided whether two quantities are in a proportional relationship.
  • In Grade 8, students begin to call relationships functions when each input is assigned to exactly one output. Also, in Grade 8, students learn that proportional relationships are part of a broader group of linear functions, and they are able to identify whether a relationship is linear. Nonlinear functions are included for comparison.
  • Later, in high school, students use function notation and are able to identify types of nonlinear functions.
