Mobile learning techniques have brought the potential of scaffolding information in real-world context that allows learners to interact more actively with their learning content. In this study, we present an interactive learning approach that allows learners to interact with their learning content in real-world context. With learning environment and tasks aligned to the learning content and outcomes, we have developed a mobile application for preschool children to experience their own learning environment using an interactive learning approach and mobile technologies Quick Response codes for learning counting and quantifying skills. The learning content is delivered to learners based on an interactive learning path and the assessment of the learners' progress to further learning. We evaluate the learning approach in a group of 34 preschool children between 3 and 5 years old, divided into intervention and control group. The intervention group were engaged in numeric learning tasks using the interactive learning approach in mobile context. The control group were engaged in learning activities according to the preschool existing program's pedagogical curriculum. Pre and post-test learning progress assessment related to the mathematical domain indicate that children from the experimental group performed better than the comparison group after four-month intervention period.
