TY - JOUR T1 - Skúmanie v školskej matematike – Magický štvorec a mobilný telefón A1 - Frobisher, Leonard A1 - Kopka, Jan A1 - Trenkler, Marián JA - Obzory matematiky, fyziky a informatiky Y1 - 2007 VL - 36 IS - 1 SP - 6 EP - 14 SN - 1335-4981 N2 - Investigation is not only a method for a teacher to use in teaching mathematics, but also for a student to use in learning the subject. We show how to construct a magic square using the numbers on a cellular phone with the help of investigation. We then consider how the same problem can be approached in the early years of elementary school giving rise to many related problems. ER - |
