A blog about teaching and learning in a maths classroom.

I wanted to play a multiplication bingo type game with a class the other day, so I grabbed two 10 sided dice (apparently you don’t need to call a single dice a “die” anymore) out of the cupboard. Then I thought… hey I have a projector and a laptop.

I knew ActivStudio had a dice roller built-in, so I pulled that up. Nice simple interface, you can roll up to 5 dice – but only 6-sided dice.

I went looking through my delicious bookmarks… nothing. So, we just used the normal dice.

Later I went looking for a dice roller online. There are a couple of options I found:

  • see “dice spreadsheet” on this page – done in Excel, but only 6-sided dice.
  • dice server (via) – for game players, but the page is really cluttered and it adds the dice without an option to turn off.
  • virtual dice (via) – 6, 8, 10 and 12 sided dice, but only one.

Still not what I wanted. ∴ make your own.

This Excel file has a setup page where you specify:

  1. the starting number on the dice
  2. the number of sides (it will then show you the maximum number on the dice)
  3. whether to show a multiplication or addition sign with the dice
  1. whether to show the answer to the multiplication or addition

The next sheet has just a single dice (where many of the options above are irrelevant) and the next sheet the two dice.

I made this in Excel, because you can use Excel fullscreen with an IWB / Projector and it’s easy to modify.

Have you found a resource on the web for rolling two 10 sided dice? Do you have any suggestions for modifying this Excel file?
