Hi,
National Archives run free video conference role play sessions for schools. They have sessions running on 8th and 9th June and 2nd & 4th November, for more information see here. The conferences support historical enquiry objectives and understanding of life in the 19th century. They last an hour, are aimed at yrs 5 & 6 and would require the children to prepare in advance. The events are fully booked for the dates above. However, when I phoned up they said there was a waiting list with nobody on it so there is a chance that there will be drop outs and the opportunity for your class to have a session instead. If you would like to be put on the waiting list email sue.seber@nationalarchives.gov.uk . You can also phone on 020 8392 5365 for more information.
