The Mathematics program at Maribyrnong provides students with essential mathematical skills and knowledge in Number and Algebra, Measurement and Geometry, and Statistics and Probability. We aim to develop the numeracy capabilities that all students need in their personal, work and civic life, and provide the fundamentals on which mathematical specialties and professional applications of mathematics are built. Teachers use the content descriptions from The Australian Curriculum to guide the selection of 'what to teach when'. These year level statements describe the knowledge, skills, concepts and processes that teachers are expected to teach and students are expected to learn. The content descriptions are intended to ensure that learning is appropriately ordered and that unnecessary repetition is avoided. However, a concept or skill introduced at one year level may be revisited, strengthened and extended in later years as needed. Our educators also use a spiralling approach towards teaching mathematics, revisiting concepts across the year at the individual levels of our students. Coupled with this approach, we make learning visible by using 'I Can Statements'; a set of statements which encourage students to set new targets for learning and reflect on their progress towards these goals.
