If you are an Indian parent living outside India and would want to educate your children on India, you should check out Teach India Project-- an initiative by a group of mothers way back in 2004 is now a successful organization. They provide lesson plans, Curriculum, teaching kit, etc. Schools also use their curriculum. I have families who often order books on India from here which do not reach them on time or have to wait until somebody from the family get there. A customized curriculum which you can use at home for your children sounds perfect to me.
