A good book for new ideas!

I bought this book ("Inglês é Teen!") a few weeks ago but I confess that only this weekend I had time to ckeck it up. I could notice that the book brings many ideas and also several activities for students with different ages. I liked it a lot! One interesting thing is that the author gives the idea of creating a blog for the students in order to make them interact and so, but I tried this idea with my students some time ago and it just didn't work... Anyway,the book is worth it because of the suggestions it has and also because of its price. It costs only R$ 35,55.
