Children in North Point enjoyed the unusual privilege of going to school in their pyjamas - in aid of Operation Santa Claus. The 250 children of Kaingsyu & Chekiang Primary School also had a fair, during which children got to play games made by Primary Six children during design and technology lessons. 'It's a lot of work but enormous fun,' deputy head teacher Philip Doyle said. 'Already, this year's Primary Five children are looking forward to next year when they can create their own games for the fair.' Primary One children read out their poems, which were recorded on CD and sold to parents. The school raised $45,000 for Operation Santa Claus. And at Singapore International School, $78,000 was raised for Operation Santa Claus by schoolchildren who went on a walkathon around The Peak. Principal Sally Thio said: 'The Christmas-at-The-Peak Walkathon raised a total of $378,792. 'We apportioned $200,000 for a school building project on the mainland, $100,000 for the earthquake victims of Pakistan and the balance of $78,792 goes towards Operation Santa.' Pupils also contributed by asking for a donation to be made in place of a Christmas present they would normally have received from relatives and friends.
