Spalding pupils have been singing along to sign language.
Pupils from Ayscoughfee Hall School enjoyed a day at Bookmark when author Gary Slack showed them the fun side of learning to sign.
Mr Slack is promoting his new book Learn to Sign with Olli, which he hopes will encourage children to pick up sign language and broaden their communication skills.
A qualified communication support worker for the deaf, Mr Slack works with Lincolnshire County Council to deliver training to childminders and careworkers.
The children memorised sign language to four nursery rhymes.
Shopfloor supervisor at Bookmark, Sally Smith, said: "It was an excellent way for them to memorise sign language and it was definitely something a bit different."
n The heartwarming tale of the creation of Paddington Bear was brought to life at Bookmark.
Shirley Clarkson signed copies of her new book Bearly Believable: My Part in the Paddington Bear Story for around 60 visitors to bookshop.
Shirley is also responsible for another famous star – her son is the journalist and Top Gear presenter Jeremy Clarkson.
Bookmark owner Christine Hanson said: "She told us that every Christmas she used to make a toy for Jeremy and his sister Joanna.
"One year she made a Paddington Bear and the idea came from there."
