You can identify your iPad by referring to the model number printed on the iPad's back case. Find out which iPad model you have on this page: iPad Models.
To start off with the difference, the iPad is slightly heavier and larger than the iPad mini. It has more hardware power, which means that it will perform better than an iPad mini. On basic terms, differences between iPad, iPad mini and iPad Air consist in design, physical size, display size, performance, and price.
If a smaller tablet or price are the highest priority, you would be best served by an iPad mini, which would likely be your best choice. If performance and screen size are highest priorities, an iPad Air would likely be your choice.
Overall if you are going to get an iPad for books and games, we would recommend the iPad mini with retina display as it's very portable, durable and is a good upgrade and very easy to get used to from a phone.
