Ntsiki has been away from school because she has been ill. She is returning to school on her birthday and the children are planning a surprise for her ... they want to make the biggest birthday cake in the world! This title forms part of the Little Library programme, which consists of a Literacy Kit, Numeracy Kit and Life Skills Kit. These were developed to respond to a need for high-quality, indigenous books for the younger members of our communities, and have been successfully used in schools for the last ten years. This title is found in the updated, OBE version of the Little Library Maths Kit, now called the Little Library Numeracy Kit. The Numeracy Kit keeps seven of the best stories, and introduces five new ones - all of them trialled in classrooms around the country. Ntsiki's surprise tells the story of Ntsiki, who returns to her school on her birthday after being ill. Her schoolmates plan to surprise her with the biggest birthday cake in the world. Process, calendar time, large numbers and data handling are the main Mathematics links in this story.
