outline for teaching to kids in 5 min intervals

We are doing a classical memory class with a group of friends and I want to change from doing Latin to Greek.  I only have about 5 mins. once a week.  I was thinking about starting with the alphabet and teaching a few letters each week until we have the song down from "Greek for the rest of us" that I already have.  I'm looking for Greek Flash cards and I'm sure I have just missed them on this site.  Does anyone know where (what link) I could go to find them.  I then thought about going to the verbs mainly just try to follow the class the best I can.  If it goes well I would love to do the class with my own kids.  Thank you
