These interactive notebook activities are intended to help students understand how to graph proportional relationships, understand that a function is a rule that assigns one input to one output exactly, compare properties of two functions, interpret the equation y = mx + b, construct a function, determine the rate of change of a function, and describe the functional relationship between two quantities.Included are:

-4 different Functions activities to engage students

-Teacher facilitated activity for 60-90 minutes of classroom time

-Activities include: Vocabulary, Completing a function table and graph from a linear function rule, Writing a rule from two points using slope-intercept form, and Writing a rule, completing a function table, and drawing a graph from a function word problem.

-Examples of Completed Interactive Math Notebook Activities are included

to see state-specific standards (only available in the US).
Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
Interpret the equation 𝘺 = 𝘮𝘹 + 𝘣 as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function 𝘈 = 𝑠² giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
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.
