How to use it

  1. The range is already set from 1 to 30. Press Hold to roll or the Space bar, and let go to land on a number.
  2. No repeats is on, so each number comes up once until all have been used. Untick it to allow repeats.
  3. For another range, type the lowest and highest numbers in the boxes, or open the full random number generator for odd, even, multiples and more.

Ideas for class

  • Give each child a number for the year and draw to choose who answers, then tap away the numbers of children who are absent today.
  • Pick a day of the month for a calendar activity: draw a number and ask what day of the week it falls on this month.
  • Choose a page or an item from a list of thirty, such as a spelling word, a vocabulary term or a question from a set.
  • Draw a number for a mystery challenge and have every child do something with it: double it, halve it, or find its factors.

Questions

How do I use it to pick a student fairly?

Give each child a number from 1 to 30, then press the button. Every number has the same chance, and with No repeats on, nobody is picked twice before everyone has had a turn.

What if my class is not exactly thirty?

Change the highest number in the box to match your class. The draw then runs from 1 to that number, and you can tap the number of any absent child to leave it out for today.
