Children were given the chance to play sport at an Olympic venue under the guidance of expert coaches.
Year Three and Four pupils from St Andrew's Primary School in Mathews Close, Halstead, took part in mini tennis and four-a-side hockey at Lee Valley Hockey and Tennis Centre.
They were among children invited from 100 schools in London, Hertfordshire and Essex as part of the first Lee Valley Schools Festival, which included cycling for some pupils at Lee Valley VeloPark.
