To make better progress with learning spoken numbers in French—the goal is to get instant recognition plus fluidity in speech—I used Random.org to create a nice list of numbers which is long enough for me to use over and over again without fear of memory effects. I then imported them into a Google sheet, added a column of periods to help pause when spoken, then had an Android all read them out. The app, I realised later had a record function, so now I have an 6MB Ogg file of 2,000 random integers spoken in French with 1 second pauses between each!

At the root of it is your service. Thanks!

Your project is wonderful; thank you for making it free and flexible for public use. I use it every day in my 7th grade classroom to assign warm-up problems to students in my class; this particular crop of kids is highly competitive and I was having trouble selecting from a group with all their hands up!

I read your FAQ and I wanted to contribute a little thought: to a computer, would it think it has free will? We store and process information in the same way; so we are running a big program which makes decisions based upon lots and lots of current states and simultaneous inputs. I suspect it is impossible to know whether we have free will from within ourselves and will have to use lots of expensive computer modeling to answer the question, but I'm guessing the answer is no.

Hi, I just wanted to tell you thank you for the die roller on your site. I am a 5th grade math teacher. I developed a lesson on comparing decimals around a game, but I forgot to bring the dice to school. Your website saved my lesson! I was able to project the die roller on my Smartboard and we were able to play as a whole class. Thanks!

I want to thank you very much for your random number generator! We teachers are supposed to check for understanding with all of our students. I am sure you are aware of all the stumbling blocks to actually calling on students randomly. I hope that your random number generator, with its ability to generate integers within the range that I specify, will help me to better sample my students for their understanding. More important to the students is the classroom jobs like setting up the technology each day, passing out folders, etc. (I teach 6th Grade in the USA.)

The most important feature of your generator is the ability to set the range/limits!

I tried popsicle sticks in a can but found that method to be ‘uncannily’ unfair! It seemed like I kept getting the same sticks!

I tried writing numbers on index cards, but I can't shuffle cards to save my life! (Besides, when I pick the cards without looking, you know there is bias in that as well … somewhere in my brain.)

I finally purchased some dice from the net that have various numbers of sides. But that didn't work either because the number of students in my class changes throughout the year as the students in our area have a somewhat high transiency rate.

I was at a loss, and the students have been getting upset with me.

In the past I have Googled for something like this, but I guess I never quite put in the correct words to arrive at your site, but I THANK GOD THAT I FOUND YOUR SITE TODAY! And, yes, you may use this testimonial!

—Shannon Clark, Los Angeles, USA

I am a teacher, and part of my student's grade is based on an in-class response to questions. I noticed that on some days, I was calling on the students who usually don't have the answers, and then on other days, I called on the better students.

To solve this, I produced a truly random class list for every class meeting. Now I don't have to think about who knows what, I just read the next name in the list.

—Jerid Krulish

Just wanted to say a quick thank you for your Random.org service. I was trying to demonstrate regression to the mean to my students and didn't have access to a statistical analysis program. So I jumped on the internet and had my numbers within a couple of minutes! Thanks!

—Bronwyn Clark

I use your website to assign random problems to the math students I tutor. Thank you very much.

—Gabriel Lichstein, Los Angeles

As part of the classes I teach, I task my students with preparing a lot of presentations. To save time & reduce boredom, I occasionally have only a portion of the student teams give their presentations. I use your Sequence Generator to pick who presents (& in what order), after they're ready to present (to keep them focused & accountable). Great website; please keep up the good work!

—Lt Col Chuck Stribula, Project Management Professional and Professor, Defense Acquisition University

I am high school student taking AP Statistics. I am using the random sequence generator for a major project studying if CSPAN has any political bias. Given the large size of their programming archive, I needed a way to randomly select which days and hours to research. Thank you Random.org!

—Alex Vincent

I found your random number generator really useful in my Maths Statistics coursework preparation for my GCSE so while I was using the web I found your brilliant site to help me along the way and made it easier than using a calculator! Thank you very much!

—Charlie Probert, Student, UK

I am a pilot studying for my instrument rating (complicated procedures used for flying in clouds and low visibility) and I use your random number generator to generate simulated Air Traffic Control clearances. I substitute the numbers in for headings and bearings. It's great practice and I hope I'll ace the exam this way.

—Trevor Brooke

I just wanted to learn more about the world. I use numbers from your site to randomly pick 5 countries to pay a little extra attention to for the year. I also use the random numbers to come up with an age and sex for an imaginary citizen in that country and try to think about the country's recent history from their point of view.

—Sylvia Johnson

I am an instructor of adult literacy and used your random numbers to generate questions in BEDMAS (order of operations) for my students. This saved me a lot of extra work and time. Thank you!

—Peter Fergus-Moore, Thunder Bay, Ontario, Canada

I used Random.org to simulate noisy transistors in circuit simulations for a school project (and made sure to credit Random.org for the data in the report!)

—Pepin Torres, Revere, Massachusetts, USA

I use Random.org to generate numbers for questions I am going to ask the kids at school. I'm a maths teacher and often have trouble devising questions (especially for data handling!). It's great to be able to specify what kind of numbers I want, and how many. Thanks for taking a load of work off me!

—Tanya Prestwood

Dear Mr. Haahr, I would like to express my appreciation for your random number generator. I used it for selecting a sample of 40 (of about 400) for my Work-Study project, a way to provide students on government assistance with money and work experience, at the Department of Classics, University of Toronto, Erindale Campus. My supervisors, Dr. Catherine Rubincame and Elaine Goettler would also like to express their thanks. I hope you keep up the good work.

I produce a high school quiz show in Dayton, Ohio (USA). Each year we can only choose 36 high schools, & we typically get about 70 schools who wish to play. I assign a number to each school, then use Random.org to generate the field of teams that will compete. It's a completely fair way to choose the schools.

—Tom Housley, Producer and Director, WHIO TV, USA

When giving a quiz or test, I like to allow the students to choose 6 out of 7 (for example) of the questions I ask, so that they can have one ‘free’ one if they don't know it. Invariably, some students answer all 7. Your website makes it so much easier to deal with this problem (and now the students know I use your site and that I won't just let a wrong answer stand for the one they should have omitted).

My name is Patrick Ayers, a Junior in high school in Florida.

I am doing a research project on voting theory, and I used numbers from Random.org to order candidates on the ballots as well as assign which group of voter would use which system of elections.

—Patrick Ayers

We are a charter high school in Chesterfield, Virginia, USA. I use Random.org to assign numbers to student applications. We always have more applicants than positions available, so the most fair way to determine who gets offered a position at our school is using Random.org to generate random sequences for a lottery. Thank you for making this process so easy for me; no one can question the fairness of your truly random numbers.

—Kelly Kennedy, Chesterfield Community High School, Virginia, USA

I used your sequence generator to run a lottery for English as Second Language Services at Northwestern University (Chicago Campus). Each year we have more students applying for tutoring slots than there are spaces available, so this year we ran a lottery to determine who would receive a slot. Thanks for making this process easier!

—Julia Moore, Director of the English as a Second Language Program, Department of Linguistics, Northwestern University

I use your random numbers to assign grades for students' exams answers. It is quicker than reading them all … No, I don't really … just kidding! Actually I use your random numbers to decide which lectures to base the exam questions on, since there is not enough time in the exam to ask an essay question on every lecture.
