The purpose of this study is to investigate if information and communications technology (ICT) helps improve students' achievement in geometry regarding solids' nets. Our research compares the achievement of the students in the experimental group taught using our ICT intervention to students in the control group taught by traditional teaching methodology. In particular, we designed a teaching intervention with educational activities, in which we incorporated Augmented Reality (AR) technology to test whether geometry teaching is enhanced. The study dealt with primary school students of fourth grade, who were divided into two groups (experimental and control). Students in both groups were pre-tested and post-tested for their achievement in geometry. The results of the study indicated that teaching and learning through ICT is an interactive process for students at primary school and has a positive effect on learning geometry as compared to the traditional teaching method.
