This would come under cultural context similar to when class stops for the Melbourne Cup allowing children some self directed development. :D. Sorry if I seem flippant but at the other end of educating children, I would say don't sweat the small stuff, education is lifelong and the parts that really define you as an adult come from experiences and doing rather than theorising. Not every person needs to externalise their learning, children are quite good at seeing a larger scope than credited for but it could be too that this teacher is of the burnt out needing to retire but cant afford it type. Maybe a chat to the teacher stating that this type of curriculum is foreign to you as you are new to this country and you are a bit worried about how it all relates. Having seen the pushy parent brigade work the teacher to the ground even as early as acquaintance night I have learned it is far easier to use this approach than join the PPB and often you get the result you are seeking.
