Get a cheap pole and reel, couple of bobbers, small lead weights and some crickets or worms. Do you have sunfish? If yes then you both will have a great time. Perhaps carp, y'all seem to have made an art out of catching them. If nothing else keep it simple and Take your kid fishing and hunting as often as possible now and you wont be fishin and huntin for him later.
"When governments fear the people, there is liberty. When the people fear the government, there is tyranny. The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government." Thomas Jefferson.
