5 Dice - An App to Help Students Learn the Order of Operations

5 Dice is a nice iPad app that provides students with a place to practice and develop their understanding of the order of operations.

The 5 Dice app presents students with a number that they have to write an equation for using all of the dice presented to them. When students think that they have created an equation that will result in the number given to them, they click "shoot" to hit the target number. If students have written a correct equation, 5 Dice will show them other equations that will also work. If they have not written a correct equation they will be prompted to try again.

Applications for Education
5 Dice is designed for upper elementary school and middle school students. In addition to the "target number game" students can simply use the app's whiteboard option to try out various ways to hit their target numbers.

A Good App to Help Students Pace Presentations

PaceRecorder is a simple Android app that records your voice and gives you instant feedback about the pace with which you are speaking. The feedback comes in the form of three simple symbols; a turtle, a rabbit, and a thumbs-up. If the turtle appears while you're speaking it indicates that you're relaxed or perhaps a bit too slow. The rabbit indicates excitement and perhaps that you're speaking a bit too quickly. And, of course, the thumbs-up means you're right on track.

Here is a demo of PaceRecorder.



Applications for Education
One of the nervous habits that most people have when they speak to a large audience is to speak too quickly. This is especially true for students who are giving presentations to a group for the first time. PaceRecorder is a free Android app that aims to help people better pace their speeches.

TinEye - Conduct Reverse Image Searches

TinEye is a reverse image search engine. What that means is that instead of searching for images by keyword you search for images by uploading an image or linking to an image. For example, if I have a picture of my dog and want to find more pictures of dogs like him, I simply upload a picture of my dog to TinEye and TinEye will search for images like mine.

TinEye offers browser extensions for Chrome, Firefox, Safari, Internet Explorer, and Opera. With the extension installed you can simply right click on any image and select "search image on TinEye" to quickly conduct an image search.

Applications for Education
TinEye's browser extensions could be very helpful for students to quickly locate images to use in presentations. As I wrote a couple of years ago, TinEye itself could be useful for teaching students to be aware of their digital footprints. You could use TinEye to show them that an image they upload to a social network could get reused in multiple places.
