This study focused on increasing the awareness and knowledge of disadvantaged students under the protection of social services about mathematics in their environment for real life situations. In this study, which was carried out within the scope of The Scientific and Technological Research Council of Türkiye (TÜBİTAK) 4004- Education in Nature and Science Camps/Schools Support Program, it was aimed to contribute to the development of students' mathematical understanding, to develop positive attitudes towards mathematics, to gain the desire to participate actively in doing mathematics and to develop collaborative learning. The sample of the study consisted of 30 students (5th, 6th and 7th grades) from 4 different Children's Homes Coordination Centres in the European part of Istanbul. This study with disadvantaged students was considered important in terms of socialisation as well as improving students' academic skills. In the project where real-life based mathematics activities were applied, the survey technique was used to collect data. In this context, different scales were used. The data obtained from the scales were analysed using SPSS 18 statistical data analysis package programme. With these scales, it was aimed to determine the levels of students as a result of their participation in mathematical activities. In addition, it was examined whether there were significant differences between the groups according to demographic characteristics such as gender and grade level. The prominent results show that 6th and 7th grade students have positive attitudes towards mathematics. It was revealed that there was no statistically significant difference between the gender characteristic and the scales applied. However, it was seen that there was a statistically significant difference between grade level and secondary school mathematics literacy-self-efficacy scale.
