My 12 yo is going to a co-op for a writing class and a science class. She'll be using MBTP for her core and then TT for math with some Life of Fred thrown in because she really likes it. 10 yo and 8 yo will be using the same MBTP. 10 yo will use TT for math as well as starting cursive. We're a little late to the game but she is really eager to learn. 8yo will be using Abeka for math as well as Life of Fred. Not sure what I'm going to do with the twins, possibly Before Five in a Row or something similar. I just need a reminder to do certain things with them, they play really well together and I sometimes forget that I want them to learn certain skills or even to read to them. So what are you doing?
