Salam Alaikum,
I wish I had good advice for you - am am facing the same problem. My organization completely sucks but I want to teach my (18 month old) daughter to read English, Arabic, and do math, as well as find a way to teach her Qur’an even though I don’t speak Arabic myself!
I agree with wetdreamer, just do as much as you can handle and your child will probably be able to handle it as long as you can keep him interested.
As for the scheduling, I’m not 100% sure either (as I said, my own organization sucks), but I have a few ideas.
For the Arabic I suppose it would work the same as English: show single words for a few weeks, and then start taking the single words that you have finished (like you showed them for ten days or something) and combining them into couplets. Continue to bring new single words at the same time that you bring new couplets made from old words.
For doing English and Arabic and the same time, maybe each day you could do two sessions, each consisting of four things: one set of English single words, one set of English couplets (when you are ready for them), one set of Arabic single words, and one set of Arabic couplets.
I think it might be interesting to even try to teach the same words and couplets in both languages at the same time! Using pictures of the concepts presented in the words might help your child see the connections between the two languages. Cat = picture of cat = قط. Big cat = picture of a big cat = قط كبير and so on.
I am using little reader to help me stay organized in English and I just realized how smart it would be for me to take whatever materials it is teaching in English and simply make an Arabic version to show a few minutes later. That would help me stay on track and on a schedule with Arabic as well as long as I can keep up with building the Arabic versions. I don’t know if you use little reader though. That might not help you.
I don’t see any problems with doing all three at once - English, Arabic, and Math, if you can handle it. That is in fact my plan. So far I have only started English and Math - the stuff that comes ready with little reader and little math, but I hope to start teaching the Arabic soon. My daughter always seems hungry for more when her math and English lessons are over, and those only last like 5 minutes all together, so I see no reason not to just add on one more section.
I hope I have been of help to you.
Salam Alaikum,
