I found this list of "attainments" (goals or achievements) that a student should reach by the time she is six. (There's also a list for a twelve year old.) These lists were written by Charlotte Mason way back in the day. I got some ideas from them. For example, I have been considering starting foreign language with Norah, but I am not sure how serious a study we can attempt at this point. I'm not sure what's reasonable to expect from a six year old. But, I believe Norah can memorize some Spanish vocabulary, a song or two and some phrases by the time she's seven. At the very least, it would be a good place to begin.
