Explaining the Concept and Operations of Integer in Primary School Mathematics Teaching: Opposite Model Sample

Many related studies have studied many different models in the teaching of the concept of integer, which have reported that counters failed to completely help with the understanding of the concept of and operation modeling in integers. The purpose of the present research is presenting the "opposite model", which is a quantitative model, unlike thermometer, elevator, sea level, or number line, which are directional models. Additionally, it presents solutions to the problem of learning the concept of and operations in integers through models used in teaching integers for primary school 6 th grade students. Opposite model is an integer model, which is based on theory and enables the easy learning of the concept of integers and addition and subtraction operations tested with experimental study by [9]. The present research is believed to contribute students' meaningful learning of the concept and operations of integers and alternative thinking through opposite model. The present research discusses the necessity of opposite model, which is to be offered as an alternative mathematical model for teaching the concept of integers and addition-subtraction operations, in light of the findings obtained through literature review.
