English language textbooks for Arabic speakers

[Mary T]

Hi there, I am part of a volunteer group sponsoring two adult Iraqi-Palestinian refugees to settle here in the UK. They have studied English at school but have not really used it since then. They will be enrolling in ESOL classes but they're also looking for some beginner-level English textbooks/courses written for Arabic speakers to help them study at home. Can anyone recommend anything? I've seen a couple of books by Matthew Preston and Kevin Lee online, has anyone come across them?

Thanks very much

Mary
