Schoolchildren have been banned from putting their hands up in class – and told to do a ‘Fonz’ thumbs up instead.
Parents blasted the rule as ‘daft’ and said the pupils at Burlington Junior School in East Yorkshire would look as though they were imitating Happy Days character The Fonz.
Helpful posters at the school show a raised arm with a thick red cross next to it and a picture of a child doing a thumbs up.
Headteacher Cheryle Adams insisted that the more positive hand signal had a ‘calming’ effect on the eight- and nine-year-old children.
