I agree with the others that you might be diving too far into the deep end here. I'm about to start teaching my 7 year old a little bit about coding and am starting with Wonder Workshop[1]. Its a suit of toys (robots) that are approachable and fun and give the kid instant feedback. Something more high level like that might help you teach your child the overarching concepts that will inform more complex ones in the future. Best of luck!
