Playway

I've been using Playway(Cambridge University Press) 1,2,3 and 4 to teach a group off young learners. I've taken it as far as I'm going to with this group so I'm now looking for another course to teach them. The students are about five years old.

I was looking at the Cambridge website and a lot of courses seem to cover the same topics/vocabulary as Playway but are presented for slightly older children.

Does anyone have any recommendations for a course or materials for Very Young Learners that would be a suitable continuation from Playway and doesn't cover to much work included in Playway?
