Prime Number Bingo: a prime number game
A clue like “the next prime after 13” is called. Find the number on your card. A free prime number game for any device. Grades 4 to 6.
🧒 Kids: Read the clue, like “the next prime after 13”. Find the number on your card and tap it. Fill a whole line to shout BINGO! 🎉
How to play
- Choose what is called (primes, factors and multiples, GCF and LCM, or a mix), the time per call and whether calls are read aloud.
- Press Start bingo. Your card is a 4 by 4 grid of numbers.
- A clue is shown, like “the next prime after 13” or “the GCF of 12 and 18”. Find the number on your card and tap it before the timer runs out.
- A wrong tap shakes the square; try again. If time runs out, the answer is shown and a new call is made.
- A full row, column or diagonal is BINGO!
What your child practices
Every call is a clue with exactly one answer. Prime calls practice the primes to 50, and factor pair and multiple calls practice 4.OA.B.4. GCF and LCM calls practice 6.NS.B.4. Children must work out the answer, then find it among 16 numbers, so they think twice before tapping.
Which setting to choose
| Setting | Example | Good for | Learn it first |
|---|---|---|---|
| Primes, factors and multiples | “the next prime after 13”: find 17 | Grades 4–5 | prime numbers |
| GCF and LCM | “the LCM of 4 and 6”: find 12 | Grade 6 | GCF and LCM |
| Mix of both | any of the above | Grade 6 | factors and multiples for kids |
Primes, factors and multiples is the first setting to try. Grade 6 children can move on to GCF and LCM, then the mix.

Tips for parents
- Use “Relaxed” timing at first. Move to “Normal” when your child gets bingo with no missed calls.
- Turn on “Read calls aloud” so your child can listen and look at the card at the same time.
- Keep a list of primes to 50 handy for the first few games.
- After bingo, look at the missed calls together and work each one out on paper.
In the classroom
Project the game and play as a class. The computer calls, children find the number on their own paper bingo cards, and the board on screen keeps everyone honest. Or let pairs play on tablets.
