In the wake of recent DCSF research, this programme explores the reasons why some pupils' progress can be slow at KS2. What's holding them back, and what can be done to help?
At Barham Primary School in west London, one third of pupils are at an early stage of learning English as an additional language, with many children entering KS2 well below national expectations.
Year 3 children at the school are encouraged to develop their mathematical vocabulary and are introduced to a variety of methods for adding numbers.
Meanwhile, in a Year 6 English class, focused marking helps pupils to work out what their next steps in writing should be.
