A.,
You are embarking on a very difficult, but rewarding journey. I have considered homeschooling my only son, who is six, but have found he needs the competition from other children his own age to keep him motivated. However, every summer I put together a homeschooling plan with lessons and activities to keep him up to speed and interested in learning.
Here is one of the most important resources I have found in determining which curriculums will work for our family:
http://www.michigan.gov/som/0,1607,7-192-29939_32383_3250...
This is a page from the State of Michigan website which is dedicated to teachers and educators with all of the curriculum requirements for each grade level. I use this website to determine where my son is academically in relation to where the state thinks he should be. I also use this as a baseline when looking at a company's curriculum to determine if our son will be learning what he needs to have a similar level of education as those who participate in public schools.
As a suggestion, you might want to consider trying homeschooling this summer and see how it goes without notifying the school system just yet. If you find the fit is not right for your family then you can put him back into school without any comments or questions from the faculty, bringing up possible feelings of failure.
If it you find homeschooling works for your family, then you can notify the school in the fall. The resources I have listed below can give you ideas on how to notify the school system.
Homeschooling doesn't work for every family, but it can be a great option to those children who need special attention because they are lagging behind or because they are gifted and bored in class.
Here's one last link I can give you, it is the database for Michigan Homeschool groups by county.
http://www.homeschoolingmichigan.com/supportgroups.html
Try to get in contact with one of these groups now so you can get an idea of what opportunities are available in your area. Opportunities differ by group and county. The parents in these groups can provide you with more resources, homeschool websites, and businesses that provide discounts to homeschool families (such as Barnes and Noble).
Here are a few books that you might find invaluable:
1. "Homeschooling the Early Years: Your complete guide to successfully homeschooling the 3- to 8-year-old child" by Linda Dobson. She has also written books focusing on other age and grade levels.
2. "The Ultimate Book of Homeschooling Ideas" by Linda Dobson
3. "Homeschooling: Take a deep breath you can do this!" by Terrie Lynn Bittner
4. "Real-life homeschooling: the stories of 21 families who make it work" by Rhonda Barfield
5. "Homeschooling Today" magazine
6. "Practical Homeschooling" magazine
I have checked these resources out of the library a number of times and have purchased the ones that I found I couldn't live without. I found the book by Terrie Bittner to be the most informative about the realities of day-to-day homeschooling and how to set up an area specific to learning, keeping records, etc.
I hope I haven't swamped you with too much information. =)
Good Luck!
