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. The sandcastle competition is a story about three teams of children involved in a competition to build the best sandcastle, and is constructed mainly around the concepts of shape and colour. Mathematical concepts: identifying, describing and copying patterns; two dimensional shapes and three dimensional objects.
