There are no official lesson plans or schedules for MCT. They recommend you take about a month or two for the grammar book. Then, you are supposed to alternate between the practice book, the writing book (sentence island), the poetry book, and the vocab book. They also recommend reading lots of age appropriate, high quality literature.
Except for the practice book, the books are all intended as read alouds. The teacher's book is the same as the student book, but with added discussion points and activity explanations. It took 10-15 minutes a day to read aloud. Then, if we did an activity, it would add about 20-30 minutes. My son needs a lot of prodding and help with focusing, but other children could probably do the activities in the writing book independently. The practice book is just sentence analysis so once they get the hang of it, it is definitely independent work. It's also the only book they write in. I skipped the vocab book because he already learned about Latin roots in his spelling curriculum.
My son and I really enjoyed reading the books aloud. Sentence Island is a nice, funny story. It's intended for gifted students so it's more conceptual than other grammar programs. There's not really any memory work. I guess gifted kids don't need that kind of repetition. I like it as a supplement for my bright (but probably not "gifted") kid.
