Pupils have needs and wishes, and usually limited resources to meet them. One of the resources for achieving a desired quality of life is money. The aim of this article is to summarise the ongoing theoretical findings of pupils’ money management and pupils’ consumer behaviour, to take a closer look at Slovenian research findings to present an overview of the research on pupils’ money management in Slovenia, and to give some suggestions for teaching money management in the context of sustainable development. It is necessary to define factors, which influence the development of pupils’ money management and consumer behaviour to teach pupils to become responsible consumers. The analysis of researches has shown that the pupils’ money management development affects the availability of money (allowance), friends, parents, school, and the media. Any purchase means a choice, also a choice for or against sustainable development. Financial education is needed to prepare pupils to live responsibly in the today’s commercial society - with the future in mind.
