The Sonlight Core A is what I have used in the past for my kids kindergarten year, but it is actually geared better as a 1st grade and when I did it with the olders we stretched it out over 18 months to help them move on to Core B at the right age. But Sonlight just announced a Core K so I’m excited to try that out on Joel. People have been asking for this core for awhile so I’m glad they finally put it together. We’re going to keep on with what we’ve been doing until I can order it when it comes out in April. Then we’ll do Core K and straight back into Core A when we finish that. So . . . a bit of a mix up in my plan but I think it will be a fun kinder year and (gasp) new books! Haha.
