My paper is a presentation of an experiment by which I tried to make the acquisition of these operations easier through the use of cooperative methods and representations. The experiment was conducted in The Lower-Secondary School of Paptamási from Romania, in the school year 2009-2010. I present the results of the experiment.application/pdfcooperative methodintegersaddition and subtraction of integersrepresentationsmaterialvisualsymbolic representationsfolyóiratcikkOpen AccessIleana Matehttps://doi.org/10.5485/TMCS.2011.0278Teaching Mathematics and Computer Science19Teach.
