We love that there is a customization option for the kits. At first, homeschooling intimidated us as a family so we weren't sure where to go. I saw Timberdoodle and used their kits as recommendations for birthday gifts. When we decided to homeschool, we knew we would go with them. We have purchased six elite kits from them and have not been disappointed at all. We really love each work in the Kindergarten kit. He loves his workbooks and being able to do art, and reading at the same time. I love that I am able to trust in a company and have them do all the work for me in terms of finding quality curriculums that are holistic. This kit has everything from emotional intelligence to math. We love it so much!
