Exponents Game

This exponent game runs from 22 = 4 on its first level to Olympic powers whose answers reach seven digits, such as 220. A small raised number hides a chain of multiplications, so unpack it before your rival does and your fighter strikes first.

What is an exponent?

An exponent is the raised number in a power such as 25, and it counts how many times the base, the number below it, is written in a multiplication. We read 25 as “2 to the power of 5”: five 2s multiplied together make 32. Picture a cell that splits in two every hour: 5 hours later there are 32.

Example: what is 3⁴, or 3 to the power of 4?

  1. The base is 3 and the exponent is 4, so four 3s are multiplied: 3 × 3 × 3 × 3.
  2. Work from the left: 3 × 3 = 9, and then 9 × 3 = 27.
  3. The last 3 turns 27 into 27 × 3 = 81.
  4. So 34 = 81, and 81 is the number you type on the keypad.

Learn it step by step

A power is a shortcut for multiplying a number by itself again and again.

The little raised number tells you how many copies to multiply. 23 means 2 × 2 × 2 = 8 (three 2s). 52 ("five squared") means 5 × 5 = 25.

Multiply the base by itself the right number of times, and type the result.

Tips and common mistakes

  • Squares grow by the odd numbers in order: 1, 4, 9, 16, 25 step up by 3, 5, 7, 9. So 72 = 36 + 13 = 49.
  • A common mistake on the mixed level is merging two powers: 23 + 22 is not 25. Work out each one first, then add: 8 + 4 = 12.
  • Make it a squares game on a walk or a car ride: call out a number from 1 to 20, your child answers with its square, then swap roles.

How to play

A power such as 92 or 25 appears with its exponent raised, and you type its value on the keypad. Other levels twist the question: 105 × 101 = 10? wants just the exponent, and 23 − 32 needs the minus key for −1. Answer first and Mushroom strikes, harder the less time you take.

Powers: the short FAQ

What does squared mean in math?
Squared means multiplied by itself, so 62 is read “six squared” and equals 6 × 6 = 36. The name comes from a shape: 36 tiles laid 6 by 6 form a square. Cubed works the same way with three equal factors, so 63 = 216. Going backwards from a square gives a square root, written √, so √36 = 6. Powers and roots are two directions of one idea.
How do you calculate exponents in your head?
Multiply in stages and keep only the running result. For 44, say 4, 16, 64, 256: each step is the last result times 4. For a two-digit square such as 232, split the number into 20 and 3. Then 202 = 400, 2 × 20 × 3 = 120 and 32 = 9 add up to 529.
How do you remember the powers of 2?
Each power of 2 is double the one before, so you can rebuild the whole row from 21 = 2: 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024. That last one, 210 = 1024, is worth knowing by heart. It is just over a thousand, and multiplying it by itself gives 220 = 1048576, just over a million.
Why does my child think 3² is 6?
Many children read 32 as 3 × 2, because the two digits sit side by side and multiplying them is a familiar habit. The raised 2 is a count, not a factor: it asks for two 3s, so 32 = 3 × 3 = 9. Writing each power out in full for a while breaks the habit: 53 becomes 5 × 5 × 5 = 125, never 15.
Is this exponent game free to use in a math lesson?
Yes, it is free for the whole class: the levels run in a browser window, so pupils need no account and the school installs nothing. For a burst of exponent practice, write 24, 42, 33 and 52 on the board and ask pupils to rank them before calculating. The answers, 16, 16, 27 and 25, reveal a surprise tie. The schools plan, charged per student, shows the teacher on one dashboard which pupils are getting faster at powers.
