Pupils have been making the most of their snowy day off
Thousands of schools across Britain have been closed because of the snow driving in from the east.
A decision on whether any school should close is usually taken by individual head teachers and the government said it expected them to take a common sense approach.
In some cases their hands were forced by the lack of public transport. In some areas, further closures on Tuesday are already predicted.
With London one of the worst hit areas, a speech on education by Conservative leader David Cameron had to be moved to Tory campaign headquarters because his school venue was shut.
A spokeswoman for the Department for Children, Schools and Families (DCSF) in England, said: "We would hope head teachers can keep schools open while it is safe for them to do so, but decisions about closure have to be taken locally by those who know the local conditions."
She added: "Parents should call their child's school, or the local authority (LA) if they can reach no-one at the school. Most LAs will also have information on their website."
In some places, such as Kent - which was badly hit early on - the arrangement is that schools contact local radio stations directly.
The county council's website in Kent collapsed under the strain of people seeking information. Some 294 schools in Kent and Medway were closed.
All Surrey schools - more than 280 - closed.
East and West Sussex - 304 closed.
Some 255 Berkshire schools closed. In Hampshire, 60 were listed as closed by the county council.
In Buckinghamshire, 218 schools were shut and in Hertfordshire about 181. The council there said decisions often depended on whether enough teachers were able to get to the school to ensure pupil safety.
"Some might be able to open, others nearby might be forced to close," it said.
This upset some children who found their schools were among a handful in an entire area that remained open - so they had to go to classes while friends played in the snow.
