Abstract: The purpose of this paper is to present a collection of problems that allow students to investigate magic squares and latin squares, formulate their own conjectures about these mathematical objects, look for arguments supporting or disproving their conjectures and finally establish and prove mathematical assertions. Each problem is completed with our commentary and/or experience from classrooms. Contact the authors: ingrid.semanišinova@upjs.sk, trenkler@fedu.ku.sk Download PDF version of the preprint. |
