It has also been examined in what ways and to what extent the various forms of teaching such as frontal, group and pair and individual work contribute to the general knowledge, thinking, creativity and co-operation in this area. It will also be shown to what extent folk tales, various activities and games have proved to be efficient in the teaching of the particular topic. Every stage of the experiment was started and closed with a test in order to find out whether the development was successful and children managed to gain lasting knowledge in this particular area.application/pdfestimationmeasurementlengthand perimeterfolyóiratcikkOpen AccessMargit Tarcsihttps://doi.org/10.5485/TMCS.2007.0148Teaching Mathematics and Computer Science15Teach.
