# Prime Numbers, a Poster

This maths poster lists the 25 prime numbers below 100, together with a short definition and a number of thought prompts.

It measures 21cm wide by 60cm in height, and can be used simply for information, or as a direct teaching aid. Its 'skyscraper' format makes it an ideal addition to any classroom.

It seems to me that shortly after they have learnt about square numbers, some children encounter a strange fascination with prime numbers. And, in many ways, primes are the easier ones to identify and work with.

In the past, I've used it with post-it notes to cover some of the numbers - this gets the children to focus on the order and magnitude of the primes.

It works great stationed at the side of a display board.

print, trim, glue, and... enjoy!

### Nice One

I really like the vertical format of this.
You mention square numbers in the description. Do you have a similar sized poster with square numbers on? Triangular numbers would be useful too.
