Learning to work confidently with decimal numbers is an important part of numeracy, needed in all walks of life. It is however difficult to master. This resource for teachers explains the mathematical, psychological and pedagogical ideas needed to effectively teach this topic. It draws upon extensive research carried out at the University of Melbourne and by researchers across the world. The resource is based around how students interpret decimal notation. The Decimal Comparison Tests enable quick diagnosis, around which targeted teaching can be built. Difficulties in interpreting decimal notation are a root cause of trouble with all decimal arithmetic operations, as well as rounding, working with significant figures and generally making sense of mathematics.
