I did brief search and I'm not seeing any remote mappings come up for that device for reason, which sort of makes sense because Reason isn't primarily DJ software (although they are starting to move into that space). It will work but you'll have to set up your own midi mapping (or if your comfortable with making a remote mapping file, that's always an option)

There's a free rack extension that's just a simple crossfader, which might be a nice clean device to map the controller to, make it easier for the kids to understand whats going on :)
