Teacher Felicia Taylor Intensive Math 8th 22 Focus 8: Introduction to Functions
Standard(s) Taught

#### 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.

Review the following standards:

#### 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 a function from a graph, equation or set of ordered pairs.
• explain that a function represents a relationship between an input and an output where the output depends on the input; therefore, there can only be one output for each input.
• identify the properties of a function written in algebraic form (e.g., rate of change, meaning of y-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).
• 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.
