Mathematics at Magill School

At Magill School we teach evidence-based ‘best practice’ in mathematics in our Reception to Year 6 classes.

We aim to provide an engaging and rigorous mathematics program for all students which is differentiated to meet individual learner needs, setting up opportunities for all students to excel in challenging, open ended mathematics activities.

Intervention to support students with concept development is put in place throughout the year. Students are identified through testing and data analysis to identify student gaps in conceptual understanding and development.

The Big Ideas in Number

Our aim for all students at Magill School is to have a conceptual understanding of number, how to think numerately and how to apply their knowledge of number to real world problem solving.

Each child is immersed in the conceptual framework called The Big Ideas in Number which supports development of understanding in number from early to advanced concepts.

Di Siemon, Chief Academic responsible for The Big Ideas in Number framework, suggests that the concepts of ‘trusting the count’, ‘place value’, ‘multiplicative thinking’, ‘partitioning’, ‘proportional reasoning’, and ‘generalising’ are the checkpoints in number sense each student is required to pass through before progressing further in mathematics.

The Department for Education SA has released ‘Best Advice’ papers in mathematics aimed to assist educators in accurately teaching conceptual stages to students. The Big Ideas in Number supports conceptual thinking in the following way:

Building Belief: All Year Levels

Building Powerful Mathematicians: All Year Levels

Understanding Number and Algebra: All Year Levels
