Teachers are set to call for 'play in the curriculum' for schoolchildren up to seven as this is more suitable than educating them in a formal way. Many children are not ready to sit down and do  reading, writing and maths when they start school at the age of four or five, according to the National Union of Teachers (NUT). At its annual conference in Harrogate, it will say schools should follow the lead of countries like Finland and introduce 45-minute lessons immediately followed by 15-minute play times. Teachers want children to have more play time to encourage greater communication and social skills . They want the UK to follow the lead of countries such as Finland which has 15 minute play time after lessons . It is also likely to say lunch and break times are being used for 'coaching and cramming', depriving youngsters of their 'fundamental human right to play' with their classmates. A resolution due to be put forward at the conference says: 'Primary schools are now being driven more and more towards a test and accountability culture which in turn makes them drive children of primary age to be educated in a formal way.' It goes on to suggest learning through play is known to help youngsters develop vital communication and social skills and that 'over-formalisation of learning can cause disaffection with school'. The motion calls on the NUT to support play in the curriculum at Key Stage 1 (five to seven-year-olds) 'to reflect the needs of the children'. Speaking ahead of the conference, NUT general secretary Christine Blower said many children are not ready for the 'formal sitting down' and 'come on let's do some work stage'' before they are seven. 'There is a question about whether we're expecting children to do things they're not developmentally ready for,' she said. The resolution, set to be heard on Saturday, also says: 'Lunchtime and break times are being used for coaching and cramming sessions, thus depriving primary age children of their fundamental human right to play and have free time to socialise with their peers.' The motion calls on the NUT to support play  for five to seven-year-olds 'to reflect the needs of the children' The UN Convention on the Rights of the Child says children have the right to play and rest, it adds. Ms Blower said: 'In Finland, there are 45-minute lessons and then they have a break. Between each teaching session they have a break. One thing about our children is that, relatively speaking, they are rushed from pillar to post. Not so much in primary school, but in secondary school. 'Having a break between lessons gives a bit of space to reflect on the lesson they've just had.' The motion calls on the NUT to campaign in England and Wales for new laws to ensure children have a right to appropriate breaks and lunchtimes. The resolution comes amid growing debate over what children should learn, with politicians and education experts increasingly calling for schools to teach values such character, teamwork and resilience alongside academic subjects.
