In a number puzzle you look for a hidden number.
Read every clue carefully and rule out numbers step by step.
Example:
I am bigger than 30.
I am smaller than 40.
I am even.
My ones digit is 4.
This is how you think: between 30 and 40 are the numbers 31 to 39.
Even and ones digit 4: only the 34 fits.
The numbers filled in show the solution.
Example
- 34
- 57
For parents
What does this exercise practice?
Read clues one after another and narrow numbers down logically.
Common pitfalls
Children often pay attention to only one clue. All the clues have to be true at the same time, otherwise the number is wrong.
How to practice at home
Make up your own puzzles in pairs: one describes a number with clues, the other guesses it.
