I've never used MFW's Kindergarten curriculum, so I really can't advise for that one, but I'm pretty sure detailed instructions are in the front of the teacher's manual.
So, here is how I prepare each school year.
First, I just briefly flip through all the books that come with the curriculum just to be a little familiar with them. Sometimes the books are Usborne books and have lots of text or columns of information or sidebars and I just want to be familiar with how the books are laid out.
Next, I get a pencil, notebook, small sticky notes, the teacher's manual, and all the books, and find a quiet corner, or spread them out on the coffee table. Do whatever works. If you have littles, you may need to wait until nap time, and spread this next part over several sessions.
I read through the front introduction section, underlining anything that jumps out at me as important. I might make a little note or put an asterisk there. If I really don't want to write in that particular TM, then I'll use a sticky note. I use the notebook to make lists of things I need to do to prepare, supplies, etc. So, if I am reading the Rome to the Reformation TM, and I see that I need certain page from The Body Book copied, I'll make a box and then write "Make Body Book copies." (I like having all my copies done at the beginning of the year. You may not feel like you need to do it in advance. Only write what you need to do based on how you like to prepare.)
I also think about what supplies I already have, and then write down any other supplies I need based on the list in the front of the TM. Some years, like Explorers to 1850, it suggests spiral bound 4x6 cards for the memory work. That's something I probably wouldn't have on hand, so I write it down and then watch prices in the Sunday sale ads.
I usually read through the introduction section more than once, trying to become really familiar with it. I want to remember when we use narration and when we use copywork and dictation and such, so reading through it several times helps me. (One big tip I have is to read through that introduction section about once every 8-12 weeks, as a reminder. I often forget things.)
Next, I go to Week 1 in the TM and look over the grid and see how it is laid out. I pull out all the books that are used that week, and as I go down each day, I find the book, read what the TM tells me to read, look at the student sheets to make sure I understand which one and what the kids are suppose to do. I might write "narrate" in each Bible and History box on the grid for the first two weeks to remind myself to do that when we actually start. Then I read all the Notes after the grid to make sure I didn't miss any important information. The grid will say "see notes" if there is information there.
If all the books aren't used the first week, I will go through the weeks until I find a week where it is used, and then read the Notes about the book and read the pages assigned for that day. The idea is to feel comfortable using the books and TM together.
I might be able to do this process in one day, or I might spread it out over several days. Then, I go ahead and read the grid and Notes for every week of the year. Yep, every one. I have that notebook handy and will write things like, "Week 7, Make boats - supplies needed. . ." This really helps me get an overall view of the year. (The second time through a year, I don't go into nearly as much detail, as I'm already familiar with the books and topics.)
Finally, I read through that introduction section again. Just trying to cement all those little clues in my mind.
After that, I have my list in my notebook to work with. I put the student sheets for each student in a separate hanging file folder. We pull them out of the folder, complete them, and then they go into the appropriate notebook in a page protector. Two sheets per page protector, one facing forward, one back, unless the sheet has a backside. It took a little bit of training to teach my kids how to do the sheets in the page protector, but now at the end of the year, I can take the sheets out and have them bound at my favorite office supply store. Then I go through my checklist and do all the prep work from that.
Preparing a high school year is similar. I read through the Daily Lesson Plans, get familiar with the books my daughter will be using, and try to get a feel for the flow of the year. Then, I go over it with my daughter so she and I are on the same page. I do use Homeschool Tracker Plus to track assignments and grades, so that is a big part of my preparation for high school: entering the assignments into HST+.
So, that's is basically how I prepare using a MFW TM. For 1st grade, I did laminate things that were used frequently: the reading chart, the math place value cards, and a few other things. For that year, I also made several skip counting charts, calendars, and other daily repetitive things and put them in a notebook for each boy, and then would go through them with each boy separately. And, for first grade I added in memorizing home phone, address, and their birthday.
Enjoy your year in My Father's World!
