Unit of InstructionFocus 8: Introduction to Functions
Standard(s) Taught

MAFS.8.F.1.2

Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). 

MAFS.8.F.2.4

Construct a function to model a linear relationship between two quantities.  Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph.  Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

MAFS.8.EE.2.5

Graph proportional relationships, interpreting the unit rate as the slope of the graph.  Compare two different proportional relationships represented in different ways.

Review the following standards: 

MAFS.6.RP.1.1 Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

MAFS.6.RP.1.2 Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship.

MAFS.6.RP.1.3.a Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.

MAFS.6.RP.1.3.b Solve unit rate problems including those involving unit pricing and constant speed.

Learning Targets and Learning Criteria

Students are successful when they can:

  • identify the properties of a function written in algebraic form (e.g., rate of change, meaning of y-intercept and x-intercept, linear, non-linear).
  • compare the properties of two functions that are represented differently (e.g., as an equation, in a table, graphically, or a verbal representation).
  • interpret the unit rate of a proportional relationship as the slope of a graph.
  • determine the initial value/ y-intercept from a table, graph, equation, or two points.

During review of 6th Grade standards, students are successful when they can:

  • understand that a ratio is a comparison between quantities.
  • determine when a ratio is describing part-to-part or part-to-whole comparison.
  • describe ratio relationships between two quantities using ratio language.
  • use ratio formats interchangeably (4:5, 4/5, 4 to 5).
  • understand rate as a ratio that compares two quantities with different units of measure.
  • interpret rate language with the @ symbol or with the words per and/or each.
  • convert a ratio to a unit rate.
  • create and interpret a table of equivalent ratios
  • use a table to compare ratios and find missing values using ratios.
