At OLSK we use VIPERS cover the key comprehension skills in line with the 'new' content domains.
The same mnemonic can be used by both KS1 and KS2 with a little adaptation.
The main differences being in the S - sequence in KS1 and Summarise in KS2 also in the Explain section.
In KS1 'Explain' is not one of the content domains, rather it asks children to explain why they have come to a certain conclusion or to explain their preferences, thoughts and opinions about a text.
In KS2 the Explain section covers the additional content domains of 2F, 2G and 2H which are not present in KS1.
