Teaching Resources and Methods

Assalamu alaykum,
we are using the UK National Curriculum again as a framework for our 'unschooling'.
I like to use Letts books amongst others but we also work well with Oxford Tree Learning, CGP, and many others. Hamdulillah A. is learning fast and love Maths above any other subjects.
He is currently learning Multiplication and Division. Mash'Allah Tabarak'Allah.
S. is learning ABC's writing and recognition of sounds (phonics). He is also learning to write numbers from 1 to 50. Mash'Allah.
I would love to start few 'serious' lessons in Geography and History but the time seems just to be so little.
Also to teach Geography and History I need the right resources. At present I don't have idea what resources I should be buying.
Well, that would be my next mission...insh'Allah.
For now...wa alaykum assalam
