Hi, for
eymp 2 4.2 read the sample chapter on
sustained shared thinking to see what it's about, how it supports children's development - EYFS outcomes and for 4.3 if you're not to be observed 'using' appropriate language in your practice you can read about the type of words and open questions that you do/could xx.
EYMP 5 2.1 is covered on page 299+ of the
Penny Tassoni handbook and also on page 18 of
talking point's learner materials
