Well, you have such a great start knowing that you love your job and by proactively trying to find ways to help you ease your concerns before getting into the classroom!
If you are not planning on using games as a substantial part of your teaching with children then I truly believe that this is the way forward. The way I have been teaching (and many others like me), is truly revolutionary compared to what I experienced in school (not THAT long ago!)
My own experiences with this have been very rewarding, with children coming to learn from me in their free time, and wanting to continue, missing me when I was gone, etc.
Also other teachers using my games have reported similar great results.
As well as looking at games on many sites, and in forums, you can receive some free on the website below.
