Number wheel 1 to 100

Why are there no numbers printed on the slices?

A hundred slices around one circle leaves each slice only a sliver wide, too narrow for a number anyone could read. Rather than print tiny, blurry labels, the wheel shows the slices as colours, and the result pop-up shows the winning number in large type. Every spin is also added to the Results list.

If your audience wants to read numbers off the wheel, use a smaller range. The labels are printed on wheels up to roughly 80 slices, and a 1 to 50 wheel is still clear on a projector. The custom number wheel lets you pick any range.

How do I draw numbered tickets fairly?

The most common mistake is spinning 1 to 100 when only 73 tickets went out. Then about a quarter of spins land on a number nobody holds. Before the draw, set To to your last ticket number. If tickets are missing from the middle of the sequence, paste the numbers you did sell into the raffle wheel instead, one per line, so only real tickets are on it.

Announce the rules before you spin: how many prizes, whether a ticket can win twice, and what happens if a winner is not in the room. The guide to running a fair giveaway covers those details for draws held online.

A guess-the-number game with the wheel

One player spins in secret, hiding the screen, and remembers the number. Everyone else takes turns guessing, and the spinner answers only “higher” or “lower”. A player who halves the remaining range each time will always find the number in seven guesses or fewer, which makes a neat maths discussion afterwards: why seven, and how many guesses would 1 to 1,000 need?

For a party twist, the closest guess after three rounds wins, rather than the exact one.

100 days of school activities

Many classes celebrate the hundredth day of the school year, and a 1 to 100 wheel slots straight into it. Spin a number and ask pupils to:

• find it on a hundred square and colour it in;
• say how many tens and how many ones it has;
• decide if it is odd or even, and name the numbers either side;
• work out how far it is from 100;
• count on from it in fives or tens.

Keep the pop-up on screen while pupils work, then press Spin again for the next round. More whole-class ideas are in spinner wheel games for classrooms.

Wheel or number generator for 1 to 100?

For one number at a time with an audience, spin the wheel. If you need, say, twenty numbers at once, or a whole list with no repeats sorted in order, the random number generator does it in a single click. For younger children who want to read the slices themselves, the 1 to 10 wheel is friendlier.
