Parents like to see phonics. Songs are an attention-getter. I suggest you look in the phonics threads (run a search in thread titles for PHONICS) for worksheets, or look at sites like MES-English. Playing a game the students like and are familiar with is also probably a good idea.
Project work looks really good in after-school open classes, in my opinion, but your kids are a bit young for anything too complicated. You might have them assemble picture dictionaries or something with pictures they've drawn or cut out, or something along those lines....
