Sample Word it outs!

Word it Out Sample

On this Friday and Nest Friday, we have two quite different activities in our Reading the World Math Class.  We are going to put to work the ideas/concepts/vocabulary/statistical problems we have worked on throughout the last five classes.  Above is a sample of a Word It Out - composite of vocabulary found in a statistical study on teens and smartphones!

You will be creating one of these for a research study that you will design tomorrow and in our next class.  The product will be a poster which will include your "Word It Out", a title of your proposed study, a description of the study, an hypothesis, sample data, and a graph.  We will be posting the posters around our classrooms.  All Math Girls will then do a Gallery Walk commenting on and giving feedback on the research study and the presentation style you used.

We will make the posters colorful and inviting to look at!

Directions will be on the computers for how to complete a Word It Out!

We will also have internet sites for you to access to get brief information on a possible research study.  Some examples which you might start to consider could be:

1. Cell phone usage among teens
2. Teen pregnancy decreasing in Milwaukee
3. Women and the political race for president - importance of women voting
4. College bound girls and studying math
5. Teens and Drugs in the 21st century
6. Girls and Drugs in the 21st Century
7. Teen emotional health - depression
8.  Gun control and the second amendment
9. Medical studies: breast cancer, weight loss bypass surgery,
10. Article in the Milwaukee Journal which describes a research study.
11.  Others that you might suggest

After our visit to the Access Center this Friday, we will practice Word It Out by creating one using vocabulary from our class.  Then you will choose your groups (4 to a group) and try a few of the internet cites on research studies.  We will have a list of these created for you to review.  Once you have chosen a study, and saved the file, and sent it to your personal email, time permitting you will create a Word It Out from one paragraph or more from the article.

Don't worry - we have directions and helps for all these tasks.  We hope this will be a fun way to finish up the next two weeks - up to our Thanksgiving break!!!!!.

November 6, 2015
Hello Math Girls!

We have an announcement to make re our next class - November 13.  We will be going on a Field trip to the College Access Center on Morgan.  You will leave by bus from Alverno and return about one hour later - therefore we will have class for only about one hour back here at Alverno.

We are going to start today with some ideas for a Gallery Walk.  A Gallery Walk will be made up of the colorful posters you will design next week and complete the week after!  Part of our celebration of working with you through five consecutive classes!!!!! (remember - incentives are given for attending all!) will be your sharing your insights into mathematics.

For this weeks blog, you will go to the following link:

The first entry will be:

Open this document.

Do problems 1 and 2 (data tables)

Choose two of the problems: one for an histogram (Nos. 3 or 4)

Make an attempt at Problem 9

OR the Challenge Problem 10-14!

Post your answers on your blog.  Use graph paper in your folder to show your work.

Next week's blog - start to think about a problem (real-world) that you could use to develop a data table and a graph!  We will research data in class.  Come prepared with your topic!

Determining the Mean Average Temperature of Alaska


“40 Below”

Almost to the point of cliche, Fairbanksans use “40 below” to refer to anything that feels “really freaking cold.” -40 degrees F, for whatever reason, is the dominant metaphor for all conversations about being truly cold in Fairbanks, and across Alaska. It’s the community paradigm for that depth of chill realized on the coldest of winter days. Though it’s unclear how this particular temperature became so indispensable (boasting its own climbing gear company), it’s definitely one of the most frequently used phrases in local discourse. You’ll hear it a few times a week, at least - all year round.

ALASKA IS COLD! 

 Determining the mean, mode, and median of a set of data is a common problem you will encounter on the ACT test.  In this blog, you will view the average temperatures for Fairbanks, Alaska. You are to:
1. Determine the mean low temperature for a year OR determine the mean record low temperature.
2. Determine the mode of the average low.
3. Determine the median of the Record Low.

Month       Av.  Low         Record  Low            
                
January
-19°F
         -60 F (1969)
February
-7°F
        -52°F (1999)
March
2°F
        -41°F (1971)
April
19°F
        -24°F (1986)
May
35°F
           3° F (1964)
June
48°F
          27°F (2006)
July
50°F
          32°F (1971)
August
45°F
          24°F (1987)
September
34°F
            5°F (1992)
October
19°F
         -27°F (1975)
November
-2°F
          -45°F (1990)
December
-8°F
          - 66° F (1961)

After you have finished your calculations, write a summary of how you calculated or found the mean, median and mode. Post this on your blog.

We have just finished a study on discrimination in the workplace. Were women discriminated against? Was the study realistic? Well - those are questions that might have various answers which is sometimes part of our being able to analyse statistical studies - sometimes on the ACT you will have to read a passage and determine if the research cited is accurately presented.

Discrimination among women has been related to "the glass ceiling." To get thought the "glass ceiling," this brief excerpt lists six strategies for women to use to break through a glass ceiling:

To get ahead and reach the leadership level you want, you need to champion and market yourself. That means proactively managing every step of your career. If you can't seem to break through a glass ceiling, you might have to work harder than others.
We can't all be exactly the type of upper management person our company wants. What we can do is develop the skills that the company values. Arm yourself with a development plan as well as the help of your boss, a strong network, and, hopefully, a mentor. You can then build and showcase the skills that will help you climb the corporate ladder. Push yourself beyond your comfort zone, and you may find new zones of opportunity.
Mind Tools: Essential Skills for an Excellent Career

1. On your blog t, list the six skills suggested by the author as possibilities to  break that glass ceiling.
2, What do you think might be the best skill for you to develop?

Hello on a Friday night....

Last class - we learned about MY STYLE -  you told us about  yourself - and then we created a chart of the whole class.  You will get those results in your folders when we move to another class.

Today while in the computer class: write

Three to five sentences - what I like about math; and if you want - what I really struggle with. Then during the week -  look at what your style was - and what the class style was - blog us a response - to what is your style in math.

Our second class

This is our second class.  Today we continuing our statistical study - using a case study on discrimination.  The blogger prompt for today is:

Does the data you viewed today lead you to a conclusion: 

Hypothesize: discrimination or not?
