Access Point #: MAFS.912.F-IF.2.AP.6b

Describe the rate of change of a function using numbers.
Clarifications:

Essential Understandings

Concrete:

  • Locate coordinate pairs.
  • Identify the concepts of steepness, rise and fall in real-life contexts (e.g., ramps, roofline, stairs, escalators).
  • Pair domain with “run” and range with “rise.”

    Different equations listed, with their corresponding input/output chart data, graph, and slope determinations.
Representation:
  • Understand the following related vocabulary: domain, range, rise, rise over run, fall, steepness, ratio, increase, decrease, positive, negative, y-intercept and x-intercept.
  • Identify coordinate pairs on a coordinate plane.
  • Identify the concepts of steepness, rise, and fall in visual images (e.g., pictures of ramps, roofline, stairs, escalators).
  • Understand that “rise over run” means vertical change over horizontal change begin mathsize 12px style open parentheses increment y space divided by space increment x close parentheses. end style

Cluster: Interpret functions that arise in applications in terms of the context. (Algebra 1 - Major Cluster) (Algebra 2 - Major Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
