I introduced my children and grand children to woodworking at about that age. Some a little younger. They took right to it. My process was like this. First get their interest by watching you start to build something easy like a small box. Ask if they want to build it. If they want to than you are good to go. Building something is key here. I always had some appropriate size tools anyway. Help them, don’t do it. If you are worried about cuts and little things buy some cut proof gloves and always safety glasses. Buy them their own and wear yours too. Build along side, yours and theirs. Do each task in order. If they mess up a piece just start again like it’s no big deal, happens all the time attitude is important here. You’ll be surprised at how quickly they will get it. By the way I have 24 grand kids. Soon I will be starting on great grand kids. The grand kids have all been exposed a few of them took to it most did not because of the computer era. All hand tool work at first. Good luck and enjoy your journey.
