I am Brazilian, and started to teach Portuguese to my husband, and now I'm also teaching to a group of 6 people, and I really enjoy it.
I use a book called Ponto de Encontro. It is the most complete book in the market, and is used by most universities and language schools. Ponto de Encontro teaches Portuguese from Brazil and from Portugal. In each grammar topic and exercise, the book explains the difference between the two versions of Portuguese.
Please contact me if you have any questions or comments, I'll be glad to hear from you.
