Cryptography was incredibly important during WWII because of the British wanting to communicate without the risk of interception by the Germans. They would talk over the radio using a code, that could then be deciphered with a cryptograph. 

In Year 3 today, we wrote and solved our own secret words and messages using a cryptograph to decode them. We applied our maths skills to write and solve problems and then found what letter the number matched up with in the cryptograph.

a	b	c	d	e	f	g	h	i	j	k	l	m
252	747	82	957	100	210	472	817	12	89	281	583	234
n	o	p	q	r	s	t	u	v	w	x	y	z
482	90	173	145	800	313	480	457	663	764	11	43	119
