I haven't started with my daughter yet but with my son I used to make him write out his own monthly financial statements. Basic Balance sheet and income statement. Didn't take long at all as there wasn't much to write. He might get some money for doing choirs or as a gift that would fall under income and maybe he would buy flowers for mom for mother's day that would be expense. Then we would track the value of his assets. Bitcoin, a couple silver and gold coins and I had a small stock market account for him but have since sold that and he just holds Bitcoin now.
