Dates, floors and appointments

Everything a calendar needs, in one path. Start with ordinal numbers - first, second, third, mostly irregular through the tenth, then mechanical, and always declining like an adjective - then learn thirty-two words for calendars and appointments, five guided lessons that build from how an ordinal is formed to how it agrees like an adjective to sentences that grow from naming today's date to a genitive birthday to a locative floor to the traps every beginner falls into, listen to a phone call booking a dental appointment at full speed, read about a date one sister must not forget twice, write about your own appointment and finally read a booking sentence out loud.
