Well, I am not into teaching, but I think kids react well to pictures and to music.
There are some picture dictionaries you could use, or you could take from sites some lessons (I had that leaf with stars where I was asked to colour them - a way to teach colours).
Sometimes they use songs (native kids would like it and would be a time to see their pronounce and a way to check for communication issues).
These are ideas, but there are books and teachers that will give good ideas. In case you don´t find them you can try someone that teaches, one that you sense as friendly and has some experience under his/her belt.
