I designed this for use with Probability simulations. It outputs a list of 100 random integers between 1 and whatever the Largest Integer is. It works well with numbers up to 20. If you use numbers much larger than 20, the histograms will get weird.
Largest integer 2 will simulate 100 flips of a coin, Largest integer will simulate 100 rolls of a die. I will be using this with 8th grade middle school students, but they are working in Algebra 1 or Geometry. If you download it, you can change it to show the trials and the Least Integer. I also see that GeoGebra will make a Frequency table, which I could have used but learned about too late.
