Key Infomation


Maths is not just about completing sums and getting the right answer. It is also about understanding, at a deep level, why calculation methods work and then being able to apply mathematical reasoning to solve problems. Our maths curriculum teaches children how to think mathematically and, in order to do this, they need to be able to:

  • Recall number facts automatically.
  • Understand how to use these facts to find out other facts.
  • Understand the number system and place value and use this information to calculate efficiently.
  • Be able to choose the appropriate mathematical strategies to solve problems.
  • Use the language of mathematical reasoning (‘if I know…then it must be/can’t be/might be…’).

At St Matthias we use ‘Maths Mastery’ across the school as a programme of study for teaching mathematics.  Through this programme, a deep understanding is achieved by covering fewer topics in greater depth. Pupils master concepts rather than learning procedures by rote. 

Objects and pictures

Children use concrete manipulatives (objects) and pictorial representations (pictures), before moving to abstract symbols (numbers and signs).

Language development

The way that children speak and write about mathematics has been shown to have an impact on their success. We use a carefully sequenced, structured approach to introduce and reinforce mathematical vocabulary. Every lesson includes opportunities for children to explain or justify their mathematical reasoning.

Problem solving

Mathematical problem solving is at the heart of our approach – it is both how children learn maths and the reason why they learn maths. By accumulating knowledge of mathematics concepts, children can develop and test their problem solving in every lesson
