Mathematics

Head of Department: David Gibbon

 

Our key objective in the Saint Ronan’s Maths department is to promote an enthusiastic enjoyment of Maths through understanding. Mathematics teaches us how to make sense of the world around us. By developing a child’s ability to calculate, reason and solve problems, children learn to understand and appreciate relationships and patterns in their every day lives.

Our aim is to promote enjoyment and enthusiasm for the learning of Maths through practical activity, exploration and discussion. We believe that children should take risks in Maths and adopt a ‘have-a-go’ approach to all problems. Giving a child confidence in Maths is key to a child enjoying the subject and being competent at using and applying it.

 

Autumn

Class 3

-Main Objectives for the year: Base line tables – 2,3,4,5,10 and 11. Secure number work – bonds, place value, counting, addition, subtraction and simple multiplitcation. To have met: division, analogue time, money, measurement, shapes and fractions of an amount. To gain confidence in problem solving and mental arithmetic. Decimals are introduced on a simple basis when looking at place value, and doing money problems. Word problems are introduced as part of problem solving.
