Resources I find are the most important:

Bible - I suggest the Life Application as it has character studies and mapsbuilt right in. I also would suggest having an extra atlas and character study resource though too. Strongs Concordance is an absolute must.

English you will need an english handbook -or- if you are doing phonics you purchase a skill book, work book and reader per year.

Literature there is about 9-12 books (depending on the age of your children) to purchase this first year, most of which do repeat throughout the years. It is not necessary to use the SOW books suggested though. You can use whichever books you choose.

There are also a few books intermixed into the lessons that would be helpful.For instance in creative writing when they are comparing Jesus to a shepherd andus as the sheep, it is suggested to read "A Shepherd Looks At The 23rd Psalm."It isn't necessary, but hey it would enhance it.

The rest of the resources are for sci/hist/geo. These vary each month basically.(Every four weeks) The easiest way to do that would be to purchase a library card and world book encyclopedia. I also purchased (as suggested) the Earth Science text book. (Either BJU or Abeka would do). The first four weeks you arestudying creation science, so those are not going to be found in a library. Since you will need to buy Christian resources to study creation science, this turns out to be the most expensive year. But, these resources and this studyhave been invaluable to our home!

I was overwhelmed with the amount of resources to buy at first. It is really a simple list though. Most of these you probably already have. I think the hardpart I had was there are SOO many books I COULD have, that sure would "help." I have to remind myself to be happy with what I do have to work with and use it. Also not to add anymore books to the curriculum than necessary. I kept trying to add things in and it just complicated our school to the point I wasn't even focusing on God's word anymore!
