This week a relative joined the Scout Association in Wales. I knew that welsh scouts wore ‘Y Ddraig Goch’ (The Red Dragon or Welsh Flag) on their uniform. I didn’t know they wore it on each sleeve, symmetrically:

This gave me the idea for a symmetry homework.

If you look at the uniformed services and uniformed youth movements, how often does symmetry occur in their badges? Do some badge styles occur in several associations? Are some images deliberately stylised to make them symmetrical? Are repeated emblems always placed symmetrically on either side of a uniform?

Pupils could also design their own symmetrical class reward badges.

From a pastoral point of view, this would be a nice way to celebrate younger pupils’ interests outside school.
