Reflection: Modeling Arithmetic Sequences - Section 2: Discussion/Notes


I used this lesson with my students to really introduce the idea of functions.  We are following theUT Dana Center scope and sequence which in my interpretation starts with this unit because of the function concept.  Just make sure that this is the focus of the following lessons.  Instead of focusing on naked problems like some do I focused on contextual problems that emphasized understanding sequence s on a much deeper level.  Here is a student sample showing that the recursive formula needs to be emphasizes.  Also the excursive formula needs attention but later on in the unit students seems to grasp this concept.

Unit 2: Arithmetic and Geometric Sequences
Lesson 2 of 6

Objective: SWBAT represent arithmetic sequences verbally, visually, in lists/tables, graphically, as a recursive rule/pattern, and as an explicit rule using Cornell Notes.

Big Idea: Represent arithmetic sequences with various models using a fun cooperative sorting activity!
