Do you really feel qualified to teach your child all of the math, english, spelling, language and writing skills, science, politics, geography, algebra, calculus, logic, and just plain good study skills necessary? If you think that you are ready to dedicate your life to your children on a full time basis, then put 'home schooling requirements' in search and begin to see what you will need to do in your state. Good luck.
first speak to the head of the school and give your reasons for doing this... they may be able to help you with regards to getting the curriculum and gude you as to what you should be teching your child..
also speack to your local citizens advice to see what they sugest.
if you feel that you are capable to teach your child... good luck
