From “calculation in mind” till “mental calculation”

Through the history of mathematics teaching in the territory of Croatia, there have been many changes, one of them being linked to the approach, attitudes and even the very name of what we call today mental calculation. Mental calculation bridge of conceptual and procedural mathematical knowledge and derives from activities at the very beginning of mathematics learning. Depending on the time and needs of society and the economy, consequences of certain educational reforms and quantitative indicators at the regional and global level attitudes toward mental calculation as part of math teaching have changed. Attitudes are often equated with the use of algorithms in written calculations, which is marginalized within mathematics teaching, either because of the over-utilized use of procedural methods of a written calculation, or because of the emphasis on problem solving mathematical tasks for the development of conceptual knowledge. This paper will give a historical overview of the approach to a mental calculation by analyzing mostly textbooks for teaching mathematics in the territory of today Republic of Croatia as well as the term used for these purposes.
