Working With Rails

Hello everyone I started building a a Children’s math site in rails
my idea is to create a rails site that teaches kids simple math + – * /
with single digits the games will be written in ruby. I was wondering if anyone had any ideas how the best way of laying out the site. I personal think sorta of a scaffold but instead new being posting a new blog it would start a new game within a subject.

adding game 1 scaffold
subtraction game 2 scoffold

any ideas would be great or anyone intrested in helping with this please feel free to email me or twitter me

Thanks Gabrielg1976
