Abstract: As tablet technology becomes more readily available in schools and primary (elementary) school teachers integrate tablet technology into their teaching and learning programmes, the possibilities for using this technology in other aspects of teachers’ classroom practices can be explored. One such aspect is assessment of students’ understanding of concepts and application of strategies taught. Educreations is an application (app) that enables the user to make notes, while recording sound. The app allows teachers to capture not only the student showing how they worked out a mathematical problem but also recording the student explaining the strategies they used while solving the problem. The study uses the think aloud method to gain insight into how the students apply known numeracy strategies to solve questions. The research design, context and the key findings from the pilot study are presented and discussed.
