In the Australian Curriculum: Mathematics "Number and Algebra are developed together as each enriches the study of the other". The content strands indicate what students should be learning and the proficiency strands indicate the types of learning experiences students should be exposed to in order to learn the content. Most of the content descriptors in Years F-6 algebra refer to a progression of patterning and finding unknowns in number sentences. We could see from this that there are two major themes running through the curriculum; that of patterns and relationships, and that of equations and expressions. These two aspects of algebra are closely linked and, as such, should be developed together (Ministry of Education, 2014).
