Door [[#|Prize]]:

A TI-Nspire CX from Texas Instruments will be given away to a lucky participant of this workshop.
Yolanda Pato won our TI-Nspire CX (photo HERE).


Explore and experience math with enabling technologies. This session will leave you with a knowledge of some slick and easy to use math tools that are [[#|free]] applications or cloud-based.

We will be examine anything at the intersection of math and tech; including pedagogy and best practices. We will play with a few interactive virtual manipulatives for dynamic visualization and maybe create our own. We will cover as many tools as we can in the allocated time. Bring your questions, thoughts, and ideas.

Participant note:

Do not fear the math part of this ... there will be little to no math instruction.
Expect a lot of how to teach math with tech as an accelerator.

This session is only 2 hours, so I will offer a brief intro and demos, but hopefully I can make this participant focused/driven.
I would love for you (yeah you Mr/Ms Participant) to [[#|drive]] this with what you need or want to see in your mathematics classrooms.

BYOD if you are more comfortable with your device(s).

You can always email me if you have something you want to discuss/demo at this session.

I also presented a full day session on Programming with Alice.

Below is a "log" of our hands-on activities at this "Math Tools and Sites" session.

  1. I (Ed Bujak) teach math in a room set up with a Harkness Table, where there is one big "table" in the room and [[#|all students]] and teacher sit at the Harkness Table facing each other. For me, the big "table" is made up of about 10 tables joined together next to each other in which participants can only sit on the perimeter. Participants socialize more, sleep less, but the teacher is at the same level with the [[#|students]] at the table. Nice dynamic.
  2. I do not have an Interactive White Board (IWB)
  3. I teach using my IPEVO Point 2 USB document camera connected to my personal [[#|laptop]] connected to my personal projector to a normal white board. I write on blank 8.5 x 11 paper with colored Sharpie markers. I write as we talk. I do not do a "page-reveal" by sliding a blank sheet over already solved problems. I scan the best sheets and post them on my wiki.These are static images, but in class there is the added benefit of watching/participating in the live solutions and discourse.
  4. I change the Windows pointers to big red ones. This is a BIG hint for presenting when the cursor is needed. Download and unzip "redcursors.zip" for the .CUR cursor files. Read "info.Big Red Cursors.pdf" file on how to configure the Big Red Pointers - high visibility mouse pointer replacements.
  5. I use the ZoomIt application to annotate anything on the screen! It also allows changing color of digital ink, the thickness, etc. along with enlarging the screen. Think of this as an ability to write on a pane of transparent glass in front of the screen.

"Technology does not teach" - Ed Bujak
[[#|Technology]] does help with exploratory, inquiry, guided inquiry, or independent practice activities.
Technology removes the boring, mundane, routine, and repetitive stuff that kills HOTS (Higher Order Thinking Skills); therefore accelerating personal learning and discovery.

This session was meant to show and practice with a few math tools & sites.
Do NOT think that is comprehensive.

NOTE: Web 2.0 Tools (no installation, no setup, nothing on computer)

installed application
application to annotate anything on the screen! It also allows changing color of digital ink, the thickness, etc. along with enlarging the screen.
Big Red
Big Red Pointers - high visibility mouse pointer replacements - very nice for presentations and projecting.
Download and unzip "redcursors.zip" for the .CUR cursor files. Read "info.Big Red Cursors.pdf" file on how to configure the Big Red Pointers - high visibility mouse pointer replacements.
Web 2.0
graphing calculator - can plot multiple functions with variables tied to sliders to investigate function behaviors, can save an image of the plot, can turn expressions on/off, expressions can be named and referenced, supports restricted domain and range, windowing supported, can save URL’s for graphs/equations/inequalities and setup like this one we did in our session: https://www.desmos.com/calculator/maq23qa8r2 - our incrementally enhanced inquiry into functions dilation (magnification, scaling) along x-axis and y-axis, and translation (displacement) along x-axis and y-axis. NOTE: this short demonstration is only the tip of the iceberg.
TI-84 SmartView
(from Texas Instruments)
TI-SmartView™ emulator software - looks and behaves just like the TI-84 Silver Edition Plus (T-84 SE+). You can also connect a TI-84 SE+ via a USB cable, run the "SmartPad" App, and hit the keys on the TI-84 SE+.
Microsoft Mathematics
installed application
(free download/install)
mentioned/discussed, but not demonstrated.
From basic math to precalculus, Microsoft Mathematics 4.0 can help you visualize and see mathematical concepts as you’ve never seen them before.
social media
Web 2.0
social media (it's better than a search engine cause it's curated ... by humans!)
  1. bookmarks - diigo (follow math geeks that you find have similar interests) - Ed Bujak;s diigo
  2. tutorials
    1. Atomic Learning TI-84 Silver Edition video tutorials
    2. Hotmath.com TI-83/TI-84 video tutorials (no audio)
    3. WatchMe Ware TI-83+ tutor
    4. mathbits - nice TI-84 family instructions with samples
    5. many more
  3. video channels (subscribe to the channel to get notified of updates with emails, RSS feeds). I do not use videos to teach, but I link to applicable video clips on my daily class log for all students to refer to for a review. I cannot do a flipped classroom due to the obvious digital divideat my school.
    1. MathTV - youtube - good
    2. TechPoweredMath - youtube
    3. PatrickJMT - youtube

    5. many more
  4. Blogs usually with an RSS feed. Use an RSS reader/aggregator such as Google Readerand click on the RSS symbol to subscribe, most RSS posts are archived.

Wolfram Alpha
Web 2.0 and Web 3.0
computational knowledge engine (curated), be sure to click on "examples", try:
  1. "chocolate",
  2. "GDP of Poland",
  3. "solve 4x - 3 = 9" and click on show steps,
  4. "Popularity of name Edward / popularity of name Keith",
  5. "GDP of USA / unemployment rate of USA"
  6. "What is the meaning of life?"
Wolfram Demonstrations
Web 2.0
virtual interactive manipulative, use for exploratory investigations into almost any topic.
download the Wolfram CDF player and install on your computer to realize the full capabilities of Wolfram Demonstrations. NOTE that it is very easy to create a dynamic virtual interactive manipulative with the full Wolfram Mathematica application, can even freely take the code from a Demonstration and enhance/alter it.
TI Loaner Program
service, equipment
I borrowed from the TI Loaner Program for my SIG (Summer Institute for the Gifted) summer classes and also for an after-school STEM club (April 2009)
TI will provide calculators and probes/sensors. They will pay for shipping to/from; no cost to you. You typically cannot borrow equipment for normal school classes and not for any extended period of time.
