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.
The pdf download is spread across two A4 pages:
print, trim, glue, and... enjoy!
