Power Bingo: online square roots bingo
A power, square root or exponent rule is called; find the answer on your bingo card. A free square roots bingo game for any device. Grades 6–8.
🧒 Kids: Work out the power or root. Find the answer on your card and tap it. Fill a whole line to shout BINGO! 🎉
How to play
- Choose what is called (powers, square roots or exponent rules), the time per call and whether calls are read aloud.
- Press Start bingo. Your card is a 4 by 4 grid of numbers from 1 to 30.
- A question is called, like √144. Work it out, find 12 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 power, root or rule to work out in your head. Square root calls practice roots of perfect squares up to √900 (8.EE.A.2). Power calls mix squares and cubes with a little adding or subtracting (6.EE.A.1). Rule calls ask for the new exponent, like 3⁵ × 3⁴ = 3⁹ (8.EE.A.1). Halving instead of rooting, or multiplying exponents, gives a number that isn’t on the card.
Which setting to choose
| Setting | Example | Good for | Learn it first |
|---|---|---|---|
| Powers | 4² + 5 is called: find 21 | Grade 6 | square numbers |
| Square roots | √196 is called: find 14 | Grades 6–8 | square roots |
| Exponent rules | 2³ × 2⁴ = 2? is called: find 7 | Grade 8 | exponent rules |
Square roots is the classic setting. Children who know their squares to 15² will find the first numbers easy; the bigger roots, up to √900, need the squares from 16² to 30².
When your child gets bingo on Normal with no missed calls, try exponent rule calls, or Power Race for full speed.
