Yes don’t worry. I did Mod 1 this past year, downloaded (cheaper) used books from the library on different topics and didn’t use the commentaries sicne my ds were 7 w/ 5 yr old tagging along. And I did download the Boy of the Pyramids which the 7yr old Loved. I did save up and get the Oxford book, but was dissappointed, we didn’t “love” it, although I referred to it myself sometimes to find other books on the topic. I have since felt much more confident in CM methods and feel I don’t even need a guide for right now, so just finding books/cds etc at library. I was even going to purchase a handwriting/cm copywork book but have decided I can do just as well with paintbrushes in water outside, whiteboard, pencil/paper/clipboard etc. So in essense, getting creative with what I have.
