Third Grade Homeschool continues with some of the same books we used in second grade. I follow many suggestions from the book, The Well Trained Mind, but I have altered it somewhat. I just couldn't do all of it. The history is great, and I follow her recommendations. But through trial and error over 18 years, I have found that you can fine tune your curriculum. Be flexible, all your children are different. Follow this link to my third grade curriculum with links to the books you will need.
Religion is easily added as part of history and with a regular scripture study.
