Abstract.Using an example of composite tasks and the teaching technique
behind them, the authors describe how primary school students learn to use modelling as part of their knowledge gaining process in education. The use of modelling during math classes is one of the pre-conditions for successful learning with primary school children as with the help of modelling children can better imagine what the task implies and better understand the relationship between different values, which enhances their awareness when deciding on what operation to apply, and so on.
The article describes different models and submodels used by teachers for task
modelling. It is noted that when learning how to solve composite tasks, children learn to reflect and acquire the ability to act inside their minds and analyze their thinking.
