Mathematics KS3
Throughout KS3 at Weatherhead, the curriculum covers the four main branches of Mathematics: Number, Algebra, Shape & Space and Data Handling. There is a keen focus on the development of mathematical skills, knowledge and understanding.
We also embed problem solving in to the heart of all KS3 lessons, ensuring students are equipped with the necessary mathematical skills which will be vital for their future.
Year 7 Curriculum
Our Year 7 students follow the Mathematics Mastery Curriculum and we work in partnership with schools across the country to ensure every student achieves a strong function in mathematics, with no child left behind.
Mathematics Mastery is an engaging and accessible style of mathematics teaching with an approach designed to enhance understanding and enjoyment as well as raise attainment for every child.
Children are encouraged to physically represent mathematical concepts. Objects and pictures are used to demonstrate and visualise abstract ideas, alongside numbers and symbols.
The curriculum provides a deep and rich learning experience, explaining concepts through a variety of representations and problemsolving contexts.
