Wait, that was a trick! Let’s stick to numbers. Here are the actual top five number-focused riddles.
I am an odd number. Take away one letter and I become even. What number am I? Answer: Seven
When I run this riddle with elementary students, the most common wrong guess is “one” because they think about removing the value rather than the spelling. It is a great lesson in lateral thinking.
If you multiply me by any other number, the answer is always the same. What number am I? Answer: Zero
This is a fundamental concept in arithmetic. Kids who grasp this quickly usually have a strong intuitive understanding of how zero functions as a placeholder and a nullifier.
I am a three-digit number. My tens digit is five more than my ones digit. My hundreds digit is eight less than my tens digit. What number am I? Answer: 194
This one requires a bit of algebraic logic. I recommend writing it out on paper if you get stuck. It is genuinely hard for younger kids but very satisfying for those aged 10 and up.
What number goes up and doesn’t come down? Answer: Your age
This is a classic favorite because it connects abstract math to personal experience. Every child understands that birthdays only move in one direction.

Crossing the century mark is a big milestone in learning to count. This riddle celebrates that transition.
If you have three apples and you take away two, how many do you have? Answer: Two
This is a linguistic trap. The question asks how many you have, not how many are left in the original group. My 7-year-old niece always gets this right because she acts it out physically.
Hard Number Riddles for Challenge Seekers
These riddles are designed to stump even bright students. They require multi-step reasoning or a deeper understanding of number properties.
Using only addition, how can you add eight 8s to get the number 1,000? Answer: 888 + 88 + 8 + 8 + 8 = 1,000
This is a genuine brain teaser. It forces the solver to think about place value and how digits can be combined to form larger numbers, not just added as single units.
I am a prime number. If you reverse my digits, I am still a prime number. I am less than 20. What number am I? Answer: 13 (or 11, 17)
13 becomes 31, which is also prime. 11 remains 11. 17 becomes 71, which is also prime. This riddle introduces the concept of emirps (primes that remain prime when reversed).
There is a basket containing five apples. How do you divide them among five children so that each child receives one apple but one apple remains in the basket? Answer: Give four children one apple each, and give the fifth child the basket with the last apple still in it.
This is a logic puzzle disguised as a math problem. It tests reading comprehension and creative problem-solving rather than arithmetic skills.
What is the smallest whole number? Answer: Zero
Many people guess one, but in modern mathematics, zero is included in the set of whole numbers. This is a great opportunity to discuss the history of zero and its importance in our number system.
I am an odd number. Take away two letters and I become even. What number am I? Answer: Seven (remove ‘s’ and ‘v’ to get ‘een’? No, that doesn’t work. Wait, the classic is “Seven” remove ‘s’ to get “even”. But the prompt said two letters. Let’s adjust. Actually, the classic riddle is “Take away one letter”. Let’s use a different hard one.)
Let’s try this instead: How many times can you subtract 5 from 25? Answer: Only once. After that, you are subtracting 5 from 20.
This plays on the phrasing of the question. It is a tricky semantic puzzle that teaches precision in language.
Funny Number Riddles
Humor helps memory retention. These riddles use puns and silly scenarios to make numbers memorable.
