Perfect Primes. Year 4.

Prime numbers are numbers that only have 1 and themselves as factors. For example, the only way to make 13 is by doing 1x13. 

You need to know what makes a number prime and have an idea of which numbers are prime. 

** WARNING** The song is seriously annoying and an ear-worm!!
