Module 3--sequences to functions

As a Western New Yorker, I am used to snow, cold, and "lake effect".  Currently many southtowns are engulfed in over 60 inches of snow in what they are calling the "snowpocalypse" and "snovember".  Luckily (?) I am far enough south that my drive home was sunny and my roads are clear.  Strangest snow storm ever!  Happy Buffalo is getting some national attention, but sad that it is under these circumstances.  I hope people are staying safe and warm!

View of downtown Buffalo--that is a WALL of snow!  Relentless storm that dumped 60+ inches of snow.  (I did not take this photo)

View of my town--not NEARLY as much snow, and dry roads!

On to the math...

I have decided to skip Module 2, and save it for the end of the year.  Has anyone else decided to do this?  I know there are connections made to regressions in Module 4, but it seemed to be more logical to continue with the base Module 1 provided and move into function work, after the intense equations and inequalities study.  

That being said, I have just begun Module 3 with my Algebra 1 students.  I am still going strong with my Interactive Notebooks, ideas for improvement and modification are swarming daily.  Module 3 seems to jump all over the place.  I am anticipating spending more time on sequences than allotted, though I am constantly trying to relate it to functions (which I know is coming up in Topic B).  

I used the "double and add 5" preface from Lessons 26 & 27 in Module 1, but I am not sure if that was effective.

What other ways do you introduce recursion?  How do you get across the necessity for a recursive formula or an explicit formula?  Do you have students memorize the "ways" to get an explicit formula based on additive change and multiplicative change?  

Also, what good INB pages do you use for linear and exponential growth?  

My INB pages for this section of the modules look like this:

Any ideas?! What's working for you?

Stay tuned, I will keep updating regarding this class and my Algebra A class (first year of a two year Algebra course).
