Great resource - easy to pick up and use: thank you.
Great Resource, I don't know what Cheese and Room_101 are on about, this resource does not suggest 1 is a prime number. Bug 1 will only have one leg, and so as the lesson rightly suggests this is an odd number of factors so 1 is a square number. The bugs with two legs are the Primes. Nice idea, well executed. Thank you for the resource Helen
As Room_101 says-1 is not a prime number at any level, including primary
1 isn;t regarded as a prime number at GCSE
