Abigail Steel (author of 'Rocket Phonics' by Rising Stars) and I discuss worries over too much micromanagement of reading books according to the design of 'other' SSP programmes and training - not ours!
This will provide lots of food for thought about the allocation of reading books for children's reading practice - which may be different according to the main teaching and learning intentions, the capability of the individual children - and professional understanding about how best to use books and support children's reading in different contexts (school compared to home):
