If you are new to homeschooling and are unsure of what homeschool curriculum to use, then I highly recommend a copy of Cathy Duffy's book "100 Top Picks for Homeschool Curriculum." This book is truly an essential guide for homeschoolers and Cathy Duffy diligently details aspects of each curricula to use. The book is geared towards Christian homeschoolers who want to ensure the products they use are Bible oriented so it may not be the best choice for secular homeschoolers.
Cathy Duffy not only looks at curriculum, but also educational philosophies and individual learning styles. Cathy Duffy has a way of speaking comfort to the beginner homeschooler who may question whether or not he or she is up to the task.
I'm sure you will find this book an incredible asset to your homeschool library.
