Hi Crystal,
ULW 4 will not be ready in the near future. For students and parents that need more direct teaching concerning writing, we recommend Analytical Grammar’s Beyond the Book Report Season 3, Essays and Research Paper.
If you have not been, make sure you are utilizing the writing rubrics at the back of the ULW Teacher’s guides. These are meant to be used at the student’s level and gradually moving to the next level (increasing expectations).
