Lesson: Function rules from a table
Lesson Objective
Lesson Plan
Standard 
6.PRA.8  Recognize when information given in a table, graph, or formula suggests a proportional or linear relationship. 6.PRA.9  Produce and interpret graphs that represent the relationship between two variables (x and y) in everyday situations 

Objective 
Essential Question 

SWBAT write function rules from a table with 80% accuracy. 
Explain how patterns suggest a relationship. What kind of relationships do they suggest? Justify.

on functions. 
Actively listening and participating in the class discussion

Explain (Guided Practice) 
A function is a relationship that assigns exactly one output value for each input value. The variables x and y are often used to represent input and output. Output = Input Present the following table to students:
Lead a discussion with students on how to determine the pattern for the input (x) and output (y).

Actively listening and trying to determine the function rule of the table 

15 minutes

Explore (Conceptual Development) 
On index cards have a function table and a matching pattern for x and y. Distribute index cards to students. 
Find their match, but before doing so they must determine the pattern (if they have the table) and if they have the pattern construct the table.
