I think another factor to consider is how many children will be using the material?
I spent about $600 last year, BUT we switched to SCM and had one child start middle school and bought Apologia Gen. Scienc new, which was about $75 I think?
BUT I plan to use it with 6 children, so once they all use it, not so bad on cost.
Most ALL of the CM type curricula are non-consumable b/c we use so many living books.
This year I think I will spend only about $400 and that includes as my3boys said buying some convenience items like copywork books. I LOVE Lighthome Pubs at CurrClick and it is all done for me. Since I buy the PDF with the copyright to reproduce over and over for my family, they are very reasonable by the time all DC use them. Of course I found these just last year so oldest won’t use but other 5 will.
Our main math curriculum, Math on the Level, is PreK-Pre-Algebra so though it cost up-front every year it pays a little more for itself.
We also subscribe to Readingeggs (gasp .. I know, but I have some children with different learning abilities and this helps them a lot and me too!) for 2 DC and IXL.com for math drills for 5 DC.
BTW, you can get a lot of things at a discount by joining Homeschool Buyer’s Co-OP, which is free to join. I highly recommend it. And using Currclick as well. Both sites also offer free items that change out often.
We use the library at certain times, but this is going to sound odd mabye, but during the winter we don’t. We have 4 DC who were born with heart disease and 3 of them complex heart disease .. we have to be careful every winter. And right now, our newest DD is considered immune deficient and we are keeping her away from germs as much as possible getting ready for her heart surgery hopefully late summer/early fall … so sadly, we don’t go to the library much as I just can’t take her OR bring the books home. Unfortunately, library books are dirty. But I love the library!!!
Just some random thoughts coming from my brain tonight!
