Portia, you addressed my concern! I have no idea what is taught in k in language arts and did not want dd entering first grade without the foundation that is laid in k. But it looks like not much is taught in k anyway. Dd definitely knows all the stuff you mention is covered in k. She can read even big words like handsome and everywhere, intuitively knows some of the funny spelling rules (spells with silent e, proper use of c, k or ck, etc.) She can read books upto level E fluently with no help and full comprehension. She has read books upto level H but with stops to figure out some of the more difficult words. With math, when she figures out things by herself, I know if her logic is correct or not and I am able to correct her if it is not. With English, I don't know the rules myself and I don't want to mislead her when she asks me questions like does y sometimes act like silent e- where and why? I thought having a book that explains all this would save me from trying to google all the time.
I checked the mct curriculum and it does sound awesome! It is pricey at nearly $200 for the level 1 set. But I may still go ahead as I might learn from it as well.
Thanks again for your reply. I relieved some of my stress over the skip.
