KS3 Spelling resources?

[caffelatte100]

I am a primary school teacher and I teach English literacy skills overseas to children who attend local school here. I have some great primary aged spellers and they have now finished all the primary spelling lists and I need to keep extending them so going through to KS3 looks logical but I can't really find anything. Is there anything?

I'm looking to buy some easy resources to use on a weekly basis. I would love a set list of words to print out, an accompanying sheet for the students, teacher's book etc.

I use Schofield and Sims workbooks and some Nelson but they aren't quite right and I am looking for purchasing something new, maybe a scheme. Has anyone got any ideas?
