### Rational or Irrational? That is the Question.

One of my favorite beginning of the year activities is a card sort that we do that reviews if different numbers are irrational or rational. Students are placed into groups of 4 and have to reason with one another about the placement of each number.

Here are a few groups placing their numbers:

Here are some example numbers we had:

Here are some finished products:

This was a great activity to get students use to classroom procedures and routines.  You can find the activity here: http://map.mathshell.org/lessons.php?unit=9105&collection=8&redir=1

The activity was in groups and went through each one large group.  I had students explain why they put them in certain categories and had a classroom discussion if they agreed or not.  Some could be put into more than one category depending on the explanation.  It was a fun experience.

### Beginning of the Year

As we come down to the final week before school starts, I'm getting back in the swing of waking up (semi) early, but still going to bed late. Since I am teaching three new preps my focus will be less on Algebra 2, but it is still my favorite class.

Sequence of Topics
We use Pearson Algebra 2 books, I try to follow the sequencing, but sometimes it doesn't make sense.

Chapter 1- Expressions, Equations, and Inequalities
Chapter 2- Functions, Equations, Graphs
Chapter 3- Linear Systems
Chapter 5- Polynomials
Chapter 7- Probability and Statisitics
Chapter 8- Trigonometry
Chapter 9- Sequences
Chapter 10- Logarithms
Chapter 11- Rational Functions
Chapter 12- Conic Sections

First Week Activities
To start out with on the first day, not all of our students have iPads yet, so we do a Math About Me to get an easy A and start the year on a positive foot. Students need ten numbers that describe themselves and their picture in the middle or on a presentation, could be digital or paper copies. If students hand in a paper copy it goes on the wall to be my first student work of the year.

Second day I am going to start with a BreakOutEDU game, to show them that this year math will look and feel a little different, I like to focus on activities and projects!

Goals
Find better ways to use the iPad, for activities instead of presenting or worksheets.
Use time more effectively, get students use to bell to bell.
Remember that math isn't serious.

Icebreakers
Mentioned above, but I do try to learn all my students names the first two days even though the shy ones might squeak through to the following week.

Class Set Up
I am playing around with different organization, but I think I've settled on groups of 4.
