I have often used the Microsoft Snipping Tool when creating tests and have previously written in using Screenr.com to record videos to flip the classroom. These two tools have been combined in a nice program that allows both full screen and partial screen picture as image or video:

Handwrite your maths equations on your laptop – the options – Wacom bamboo

I have previously suggested the PTPen, although on testing the accuracy was not quite good enough to make it a perfect solution. I used to have a tablet PC that I loved but now need a new solution. I have used an Epson Brightlink projector, but the resolution of the pen was not good enough for writing in OneNote or Word using the inking pens available.

I have recently acquired a Wacom Bamboo CTH-470. I have also purchased a wireless module, so have the flexibility to be connected via USB cable or work within about 5-6m from my laptop. As long as you are looking at the projector screen, it becomes quite easy to write on the bamboo and see it come up on the projector. I was a little disappointed when I first got it out of the box that only part of the black area is actually active and usable – but I am now used to this. I rarely use the touch option and therefore the model without touch CTL-470 could be preferable for the cheaper price.

 

I bought it at Officeworks, but have also seen it at Harris Technology. (About $180 including the wireless module)c

 

Overall a great solution in the classroom and also writing up solutions.

 

Note: the CTH-670 is larger and has a larger writing area. I think this could be better, but have not used it myself walking around the classroom.

 

I have not investigated the professional intuous5 as they are more expensive and these consumer products suit my needs. If you've got any more questions, just ask in the comments.

 

Troubleshooting: occasionally the wireless drops out. If I unplug the wireless unit and plug it back in then I am back up and running in about 20 seconds.

An easy free way to use any printer connected to Windows PC to AirPrint from iPad or iPhone,

After much search and trying to install AirPrint as a service and not wanting to pay for FingerPrint, Netgear has recently released Netgear Genie. It is very easy to setup and allows you to AirPrint to any printer connected to a windows PC (it doesn’t even need to be shared). The software is also designed to let you update settings on a small range of Netgear routers (mine is not supported).

 

Highly recommended.

A full windows PC, running a full operating system that can deal with processor intensive applications such as photoshop.

Built in stand and absolutely awesome keyboard cover (like the iPad one, just better because it has a keyboard)

AirPlay Mirror iPhone 4S / iPad to a Windows PC! It is now possible – no apple tv required!!

For a long time (about 9 months since I got my iPad 2) I have wanted to AirPlay straight to my laptop which is connected to the projector in the classroom. After considerable searching I found a few semi-reliable apps that would AirPlay sound or video, but they would not allow mirroring.
In May Airserver released a PC version of their software which allows wireless mirroring straight to my PC laptop. It is currently in beta, but available for purchase and free updates are promised (not that I have needed any). There is no sound at this stage, but on its way.
I purchased a teacher educational license for USD$5.99 through PayPal (you need to change your primary PayPal email address to be one that contains .edu) and now I have a license for 3 computers. I’ve already installed on my work laptop and my media center and it is working fantastically!!
The app on the PC opens when mirroring starts and closes when you turn mirroring off.
Applications:
I love to photograph students work – their way of solving problems or group work that they produce and project it straight on the board for others to see. Using my iPhone 4S / iPad makes this easy now and I no longer require an apple tv to get the job done.

Google now graphs equations, just like wolfram alpha

Leave a Comment Written by Joshua Harnwell

Having the unified search field in google for images, websites or just about anything just got better. We knew previously that google would complete simple numerical calculations – the “google calculator”.

 

You can now graph functions from the google search box. Just put a comma between the functions.

Convert web pages to PDF files from laptop or iPad to save for later – 2 tools

Jan03

1 Comment Written by Joshua Harnwell
As I am using my iPad more and more often, if I want to archive a site and keep a copy of it, it is difficult to copy the text and pictures out and put it into a word document – which is what I would do on my laptop. 
 

  1. Use http://www.web2pdfconvert.com – simply enter the URL of the page you would like a PDF from and it will convert for you (I have had some problems getting the PDF back using this method from my iPad)
  2. Web2pdfconvert has an email option. Simply send an email to submit@web2pdfconvert.com with convert as the subject and the URL in the body of email. The PDF of the web page gets emailed back to you within a couple of minutes (this is good for storing them in the archive of a gmail account, or to review later when you get to a laptop and access your email. You can also use the “open in…” function as described below)  
  3. There is an iOS app that simplifies the process. Url2pdf is a very simple app and only includes a field to enter the PDF and a button to start the convert. It opens the pdf in safari once it has converted it.  

 
 
I then save these files to Dropbox. Dropbox is online storage. You can access files directly from your mac, pc, iOS or android device. You can also seamlessly transfer files between these platforms. You get 2GB for free. 
 
 
If you don’t have a Dropbox account, click here to sign up (you also give me a small amount of extra space if you use this link)

Shikaku – a great game to investigate areas of rectangles. Online flash or iOS app! Is this the new sudoku?

Dec29

2 Comments Written by Joshua Harnwell
 

I recently read this post over at Mathing… about Shikaku. Being the Christmas holiday break, i like to have a few puzzles to do while relaxing. I love this new game.

 

Rules:

  • Each number must appear in one and only one rectangle.
  • You must use enough rectangles to fill the playing board.
  • The number in a rectangle is the area of the rectangle (or number of squares that it takes up). E.g. a 10 could be in a 1×10 or 2×5 rectangle.
 

You can go to this flash site to play online, but given that I am using my iPad more than a desktop these days (a non flash friendly device) I had to search for an iOS app and have come up with the following free app: Shikaku that has about 20 free puzzles. There are also some additional puzzles, they come at a price of 50 for $2.99 e.g. Shikaku #1

 

Application to Teaching This would be an excellent activity to investigate areas of rectangles with a Year 7 class. You could also look at potential links between area and perimeter. Students could come up with their own modified game where numbers represent perimeters.

Microsoft Word plays friendly with inking again – here’s my fix to ‘delete all ink’.

Dec10
2011
1 Comment Written by Joshua Harnwell

When Microsoft launched Office 2010, they destroyed inking in Word. I use a Toshiba Tablet PC (a must for any mathematics teacher!)

It allows me to create my worksheets (topic-based booklets) in word and then write directly on the screen with my toshiba supplied pen. I turn the pen over and it is an eraser (like an old fashion pencil) — this ease of erasing was broken in the initial release of 2010, but now it’s fixed!

Now there’s just the problem of not being able to delete all the ink in a document. Thankfully there is a fix for this problem to get that button back. Just watch the short video below.

Using Geogebra on the spur of the moment with your class – resources to come!!

Nov27

Leave a Comment Written by Joshua Harnwell

There are two main ways that Geogebra can be used in the classroom. The first way, and potentially the most powerful way is what has been referred to as “The incidental use of Geogebra”.

You do not need any preparation for using Geogebra in is manner and it is also more student focused than the more traditional approach.

Example:

  1. Students graph the equation y = 2x + 1.
  2. Change the 1 with some other numbers to see what happens to the original graph
  3. repeat the above process with the graph y=x²
    And xy = 2 to confirm or modify your original hypothesis

In a very short space of time, students can quickly understand that if add a constant to a function, the function moves vertically by that constant.

Pros: Little preparation required, students gain a good understanding as they are manipulating the graph themselves

Cons: The teacher has to relinquish some control to the students, all students must have access to Geogebra (or at least one between 2)

Resources for Geogebra

The second use of Geogebra is prepared resources that the teacher can project onto the whiteboard (IWB) may be beneficial, but not necessary. (I’ve posted previously about how to use an IWB, if you don’t have one and also how to use a stylus on your computer to make it a tablet)

Stay tuned for some prepared resources over the next few days.
