Volunteer Simon Davies has soon settled into life at the Happy House and is proving a class act in school.
Simon, who grew up in Blackpool but now lives and works in Edinburgh, has been assisting teachers and is pictured here taking pupils for some start of term maths revision,
And is looks like it's adding up to an interesting lesson.
Thanks Simon for being a much-needed extra pair of hands.
