Uses the first 26 prime numbers to code the 26 letters. Each number is formed by multiplying the" prime numbers" of the word.
This is a challenging task and really makes students think about how to be sure a number is a factor.
Discussion of "good practice" eg
ends in 0, 5 and 2 are factors.
start with the vowels first.
use the words you have to guess the rest!
Bit of cross curricular too...anagrams...who would have thought vowels is an anagram of wolves?
Comments welcome. I have to say I love using this.
The sheet is A4 with two the same on it.

A nice resource which I will be using with my class next time I teach prime factor decomposition. Thanks for sharing :-)
