Chapter+Six

**Chapter Six - Exponentials**
This is a good activity to introduce expo growth and decay...stacy** [|growth and decay M&Ms.pdf] BASHFORD's for April 7 and 8:LESSON: [|APR7and8.ALG1.6.1RecursiveRoutines.notebook]
 * 6.1 - Recursive Routines

BUG INVESTIGATION [|DA 6.1 Investigation.doc]

We actually touched on Recursive Routines when we covered fractals and Koch's Curve. I'm not sure if we want to go back to that or push beyond it, but if you want to revisit those lessons again for some spiraling, I'm all for it. Maybe we could try the bug investigation. //__Investigations__ Bug Investigation: Pg 333.// __//Homework//__: [|Alg1 - RecursiveRoutines.pdf]

Exponential Growth lesson part I: (takes a long time to load)
[|Alg_ExponentialGrowthpartI.notebook] Homework: Find and list ten things in the real world that grow exponentially. Explain how you know that the growth is exponential.


 * 6.2 - Exponential Equations**

Again, this is Koch's Curve from before. Check out the investigation below if you want to revisit it. If not, use the notebook lesson for some "bare bones" introduction to exponential Equations!

Review Exponents (to get ready for 6.3) [|Review of Exponents.pdf]

[|Exponential Growth_HW.doc]


 * 6.3 - Multiplication and Exponents** / **6.5 - Division of Exponents** / **6.6 - Zero and Negative Exponents**

Dr.Burger Video...10 minutes! This is a good investigation put together last year. It's a solid LOYO where the students can discover exponential properties on their own as well as work out a few example problems at the same time.

 * 6.4 - Scientific Notation**

//__Notebook Lesson:__// [|Alg1 - Scientific Notation 2.notebook]

The lesson above does not go over really small numbers, so I changed the lesson up a little. I am going to do 2 days of Scientific Notation. (Annie)

[|6.4_ScientificNotation#1__2010.notebook] (fixed on April 15th...7:43 pm) The answer to the human body problem: code 3 quintillion, 750 quadrillion code [|6.4_ScientificNotation#1__2010.pdf]

Robble's Scientific Notation homework: [|ScientificNotation.doc]

Day Two of Scientific Notation: Teacher's lesson:[|6.4_ScientificNotation#2_2010.notebook] Student Lesson: [|6.4_ScientificNotation#2_2010.pdf] Homework: Find a real-world problem that utilizes Scientific Notation on the internet. Print it out and describe what the problem is pertaining to. Videos to help you understand: How to Apply Scientific Notation to Real Life

Optional 6.5 and 6.6 6.5 Lesson (this is SHORT! - I am not sure if teachers will be using this on a traditional day or a block day. If you are using it on a block day, couple it with 6.6 below): [|6.5DivisionOfExponents.notebook] [|6.5_DivisionOfExponents.pdf] [|6.5_DivisionExponents.pdf] - Skip #3 Answer key is below (see after 6.6)
