I’m so glad you like our materials! We try hard to make Charlotte Mason’s method of education accessible for homeschoolers.
You are correct that Individual Studies for grade 9 will not be released until ULW 4 is written. We do have our recommendations for math, science, Latin, language arts, and personal development available in our Curriculum Overview Chart. If you click on Grade 9, you will see our recommendations for that grade. We will be updating our science recommendation to Berean Builder’s Discovering Design in Biology in the near future.
Lessons for math and science may take your student 45-60 minutes each day, but most everything else would have lessons similar in length to grade 8.
