I’ll just add what has worked for us through the younger years. Enjoy the journey!
For Kindergarten, I would keep it really simple. I over-analyzed with my oldest and bought a canned curriculum that he and I didn’t enjoy. I wasted money on what I had heard was the “best”.
Your daughter is still really young, but depending on her interest and abilities, over the next year you might want to:
-Read-Aloud -read a lot and from many different genres. Read literature (my kids look forward to their bedtime literature with daddy. He’s been reading them chapter books at bedtime for years). Read kid-friendly biographies of famous people. Read informative and engaging science books with great illustrations. Read poetry (Favorite Poems Old and New is a great collection to have). Use the books listed on the SCM curriculum guide as just that – a guide. Explore your library and take out books that interest you.
-Reading -most kids aren’t ready to start reading until much later than 4.5, but in my kids it ranged from age 4.5 to age 6. Don’t overthink and insist on buying a complete “learn to read” curriculum. Choose a method that you think will work with your daughter. With one son I did strict phonics; with another I did simple phonics and read-aloud with him from there; with my daughters I did simple phonics and then (gasp!) they both decided they loved the Explode the Code workbooks. Whatever works!
-Handwriting – there are many websites where you can print handwriting worksheets. You can make ones that have her name, that have the Bible verse you are learning for the week, that have a few lines from a favorite poem you are reading, etc. Again, simple but effective.
-Math – For us, math is a subject that I can’t spend a lot of time doing with the kids, because I have four kids at several different levels. I try to give my kids a foundation with a good program like Math-U-See, but at your daughter’s age I would just play simple math games – war with a deck of cards, board games that incorporate simple math (even rolling two dice is adding!), and general math from around the house.
-Science/Nature Study – It’s great that you already do nature study! My kids and I are having lots of fun with the Pond and Stream Companion from SCM. That, along with several of the other SCM offerings, could be a nice supplement to what you already do. Again, make use of your library! My library only had a few of the titles for the Pond and Stream study, but they have a generous interlibrary loan, and there are books on their shelves that I can also use as a substitute.
-Bible – I would suggest getting into the habit of memorizing Bible verses. For us, because our church follows a liturgical cycle with the Bible, we always learn a verse that will be read during our Sunday services. I recommend using the Scripture Memory Box. Again, simple and effective!!
