1) I've learnt how to find out whether the number is a number without dividing number by number
2) I've learnt more characteristics of prime numbers
3) I've learnt how to use the sieve method to find prime numbers
4) I've understood that all prime numbers are odd other than the number 2

4 key learning points

~ To know if no. is a prime, divide by 2, 3, 5, 7, 11 or 13
~ Not all odd numbers are primes
~ Prime numbers are not divisible by any number except for itself
