About the Random Number Generator 1–20
Twenty covers a typical small class or a set of numbered cards, which makes 1–20 a favorite range for calling on students by number. It also works as a quick stand-in for a 20-sided die in games and reading activities.
Ways to use a random number from 1 to 20
Call on students by number
Give each student a number and use No repeats so everyone is called once before anyone is called again.
Pick a question
Number the questions on a review sheet 1–20 and draw which one the class answers next.
Addition within 20
Draw two numbers and have students add them, or find the difference between them.
Game die
Use 1–20 in place of a twenty-sided die for review games and reading challenges.
Frequently Asked Questions
Can I pick several students at once?
Yes. Set How many numbers to the group size — say 4 — and turn on No repeats so all four numbers are different. Draw again for the next group; students already picked stay out until Start Over.
Can I show it on the classroom board?
Yes. Press Classroom Presentation Mode to fill the screen with the number and hide the ads. Space or Enter draws again, which also works with most presentation clickers.
