Reflection: Intervention and Extension Building Functions - Section 2: Opening


This lesson is a great time to introduce students to Summation Notation.  IMP has an excellent lesson on consecutive sums in their Year 1 curriculum.  I like to show students summation notation because it's pretty straight forward and I think students feel they have really learned something complicated because of the way the notation is written. Though it's not usually included in a typical Algebra 1 course, I think summation notation is a nice concept to add here.

Building Functions

Unit 7: Functions
Lesson 4 of 11

Objective: SWBAT identify functional rules for patterns. SWBAT find and use rules for In/Out tables.

Big Idea: Students are challenged to move beyond identifying recursive patterns and write general functions. Next, they work fluidly within tables, finding y when given x and then finding x when given y.
