Maths is taught every day at Holy Cross. The school uses the scheme Maths - No Problem! which is a series of textbooks and workbooks written to meet the requirements of the 2014 National Curriculum.

The focus of the series is on teaching to mastery. This research-based approach emphasises problem solving and utilises pupils' core competencies to develop a relational understanding of mathematical concepts.

Maths – No Problem! is recommended by the DfE and its textbooks and workbooks are designed using decades of research to ensure a deep, secure understanding of maths in learners of every attainment level.

Pupils also have a daily Big Maths session. Big Maths sessions aim to increase pupils’ quick recall of number facts and help them to develop mental agility in maths. The sessions are fast paced and require pupils to react quickly.
