In a number riddle you look for a hidden number.
Read every clue carefully and narrow the digits down step by step.
Example:
I have 3 hundred thousands.
My ten thousands digit is 8.
My remaining digits are 4, 5, 1 and 9.
This is how you think: 3 hundred thousands means the number starts with 3.
With ten thousands 8 and the remaining digits only 384,519 is left.
The numbers written in show the answer.
Example
- I have 3 hundred thousands.
- My ten thousands and thousands digits are 8 and 4.
- My hundreds, tens and ones digits are 5, 1 and 9.
Solution: 384519
- I am greater than 500,000 and smaller than 600,000.
- My ten thousands and thousands digits are 2 and 6.
- My hundreds, tens and ones digits are all 0.
Solution: 526000
For parents
What does this exercise practice?
Reading clues one after the other and narrowing down numbers up to 1,000,000 logically.
Common pitfalls
Children often pay attention to only one clue. All clues must be true at the same time, otherwise the number is wrong.
How to practice at home
Make up your own riddles in pairs: one describes a six-digit number with clues, the other guesses it.
