ime think about what you think is important in school. what would you improve? what would you spend money on in school if you had a budget?
have a think about SEN, EAL, parent/school relations, SATS, cross curricular projects, behaviour management and your views/ideas on them etc.
quite a lot of the questions were directed on what we felt about these issues.
also, have a think about some lesson ideas:
literacy: storyboards, drama, collective storyteling
maths: games with dice, arranging a numberline, ladybird pairs
science investigations: sorting materials into hoops, magnetic or non-magnetic, conditions for growing plants
and so on.
you'll probably have to present a lesson idea for a particular objective, sometimes it helps to have a few techniques in your head which can be applied to many different lesson objectives iykwim.
but also don't worry too much, you'll be fine!
