I'm using the first grade curriculum for my second grader and I am pleased with his progress since switching over to the Spalding system. I am taking the on-line course for home schoolers as well. My question...my son has always struggled some with hand writing. We have started his spelling/vocabulary notebook in the pink primary notebook, but we have both noticed he does much better with his letter formation/sizing with a narrower line. I think the 5/8" line makes him feel as if he is drawing his letters rather than writing them and therefore, he doesn't feel as if he has very good control of his hand writing. At this point, do you think it would be wise to move him over to the blue intermediate notebook even though we are doing the first grade curriculum?
