This is not an all inclusive list as the majority of homeschool resources are Christian Based. These are just some of the programs we gleaned from and adapted the parts that fit for us. Many of these programs can be modified for a more secular approach.
A2 (A Squared) (One time cost $)
Is one I had picked up many years ago that has each grade level lined out on one disk so it is simple and covers each subject. It can easily be adapted to a more secular lesson plan. It seems that the site is no longer active, but you can find the archived copy below, and if you can find an old copy, it is a great addition to your library.

A.C.E. Accelerated Christian Education
A.C.E. provides Bible-based K–12 curriculum, consisting of reading programs, core curriculum, and electives. A.C.E. stands out from other curriculum providers with its individualized, self-instructional, mastery-based approach. Core curriculum provides students with academics, skill building, reading practice, character and wisdom training, and knowledge of God and His Word. This complete package begins with reading development and progresses through high school, giving students a solid foundation for pursuing their life goals. Students who are more skilled may progress at a faster rate or may accelerate in the areas of their academic strengths. Slower students are encouraged to do their best but are able to work at their levels of proficiency and proceed as they are capable. Each core subject consists of 12 PACEs (Packet of Accelerated Christian Education) per level. Typical students work daily on one PACE in each subject and may be performing at varying levels. The diagnostic test results help to identify academic weaknesses and prescribe a path to help students catch up. Most students complete at least 70 PACEs per year, while maintaining academic balance by completing about the same number of PACEs in each assigned subject.

You can simply visit an earlier lesson and begin at whatever point you are ready (see “Your site says I can start lessons at any time. How do I do that?” below for details). Classes are presented in a variety of formats. Almost all classes have a written component.

Winter Promise ($$)
Core Elements of a Charlotte Mason Education. WinterPromise is more than a unit study, more than a literature program, and even more than Charlotte Mason. We are in fact all of these, and more besides. We utilize these learning methods and ideas, as well as adding in some workbooks, a flavor of the “classical” method, and integrate technology. In addition, rippling throughout the curriculum are activities based on “Multiple Intelligences” research. In essence, we’ve taken the best of all these approaches and left behind the downsides. The result is a cohesive “mosaic” of learning, a multitude of “Experiences” — many different small pieces that together form a wonderful learning opportunity and a chance to build your family culture and make some memories! This “Experience Approach,” then, relies on wonderful literature, fantastic do-able activities that support intelligences goals, repetition that is exciting (not simply repetitive!), and a “joy of learning” approach.
