# Histogram Sorting Using Cooperative Learning

CAUSEWeb really does put out some great activities for teaching Introductory Statistics, such as Histogram Sorting Using Cooperative Learning.  In fact, they have an entire Statistics Activity Webinar Series that they do regularly.  I was told that this particular activity would easily be modified for the college classroom (where we sometimes don’t have as much time).  My modification is below.  The file includes a student instruction sheet, three pages of student ‘cards’ and three pages of solutions for the instructor.  Enjoy, and make sure to check out the  CAUSEWeb Statistics Activity Webinar Series!

# NOIR: New Statistics Game

NOIR stands for Nominal, Ordinal, Interval, Ratio, and is a game to help students distinguish between the four different levels of measurement.  I had been working on this game all week, and I finally had time for my students to play it in class on Thursday.  After the game, they filled out a review form for the game.  I have already tweaked the game slightly based on their feedback as the cards were not originally numbered, so it was very hard for the answers to be checked.  The students wanted the definitions on the game board somewhere, but I think that having the definitions there would defeat the purpose of helping them learn the definitions.  I did let students use notes during the game, but after they started to get used to the definitions, I saw less and less flipping through the book and notes.

Each group of four students (two teams of two students each) was given two game boards and were asked to play two rounds of the game before filling out the feedback form.  The entire process took about 30 minutes, although I had to cut some groups off in the middle of the second game because we were running out of time.  Surprisingly (to me at least), the students were actually somewhat angry about that!

If you use this game in your class, I would love to hear your feedback!

# Pricing Mistakes Challenge

I challenged my students this week to find pricing mistakes. For example, mistakes such as .11¢ instead of \$0.11 or 11¢.  I found two of my own this week.  Here they are:

# Five Quick Classroom Ideas

I’m not sure if I’ve been absolutely clear on this or not, but my lack of posting lately can be attributed to the fact that I’m now posting a majority of the links I find now on my Scoop.it page (http://bit.ly/mathnews).  Nevertheless, here are five quick ideas that just didn’t fit in over there:

1.  Create a Magazine Cover (http://bighugelabs.com/magazine.php) — In one of my Pre-Algebra courses last year I had students create a magazine about a chapter in the textbook.  This website would have helped the groups easily make a professional looking magazine cover for their project.

2.  Create Printable Posters (http://www.blockposters.com/) and (http://homokaasu.org/rasterbator/gallery.gas?937) — In one of my Beginning Algebra courses last year I had students create math ‘movie posters’.  Since I was working at a design school at the time, the students had the luxury of having access to industrial poster printers.  These websites would help in cases where students do not have access to those.

3.  Free Podcast Hosting (http://www.podomatic.com/login) — You would not believe how many times I have said that I want to start podcasting my classes, but I did not have a place to host them.  I think that I will definitely be checking this website out in the near future.

4.  Math Games for Developmental Math (http://www.aplusmath.com/Games/index.html) — Personally, I loved the MATHO game so much the first time I played it on the web that I was willing to pay \$0.99 for the APP to entertain myself on my Android Phone.  But that may be because I’m really just not an Angry Birds kind of guy.

5.  Math in Everyday Life Videos (http://www.gamequarium.org/dir/SqoolTube_Videos/Math/) — Yes, I know, the last thing we all need is a link to more math videos.  The only reason that I thought that this site stood out is because of the organization of the categories, including a category for ‘Math in Everyday Life’.

# Demo of Foldable Fraction Activity

Last week someone suggested that I try using ‘Foldables’ in my classes, but I didn’t know what those were at the time.  So, I decided to do a little research, and this is what I came up with.  I can send the template to you as well, if you would like.

# How Do You Feel About Math? Activity

I eluded to the fact that I was going to do this activity last week on Twitter.  And here are some of the pictures that students picked out of magazines to describe the way that feel about math.  Yes, there are more pictures than comments, but one of the comments ‘Math makes me feel crazy’ was used to describe a few of the pictures.  Overall, I think the class had a good time with the activity.  I learned a lot about the students and the students learned a lot about each other.  Also, I think that it made the students feel a little better knowing that they aren’t in a boat by themselves when it comes to how they feel about math.  So, I would definitely recommend doing this activity in your own classroom.

‘Math makes me feel like I need a drink.’
‘Math makes me feel crazy.’
‘Math makes me want to jump off the edge.’
‘Math makes me feel like I’ve been knocked down.’
‘Math makes me feel like my brains been taken to the cleaners.’
‘Math makes me think that is an never-ending stream.’

# Thought-Provoking Proportion Challenge Problems

I totally meant to share these problems a few weeks ago, but I wanted to try it out with my classes first.  However, I got so distracted with doing my Capture & Recapture Lab that we never got to the worksheet.  Yes, I did a Capture & Recapture lab for my Beginning Algebra Classes to help demonstrate how proportions might be used as part of a method of estimation.  Several students told me that without the lab, they wouldn’t have really understood exactly why we even needed proportions.  That made me happy.  So, here we are after the semester has already ended and I never used these problems.  But I thought that I would share them anyway.

# New Slope Game

I hope you enjoy this game!  I would love to have any feedback if you decide to use it.

Other Slope Resources

Applets
1.  Interactive Slope Applet – Although I ran out of time to actually use this with my own class, this is a wonderful resource that lets students click and drag points such that when the line between the point changes, the calculation of the slope of the line also changes on the screen as well.  Very useful!

2.  Slope-Intercept Equation Applet – This appears to be the exact same applet I introduced to you a few weeks ago in the Geogebra Tutorial video.  It’s a very simple resource that allows students to visualize the slope-intercept equation of a line by using sliders to change the slope and y-intercept.

Worksheets

# New Activity for Prime Polynomials

This is what I am going to use with my Beginning Algebra students to reinforce the idea of prime polynomials.  The majority of the polynomials are prime.

# New Game for Evaluating Functions

Here’s the new game I created for evaluating functions.  I haven’t played it with any students yet, but it has gotten a couple of test runs, and seems to be a hit among the instructors that have seen it.  If you play it, I would love to hear your feedback.  Enjoy!
