Purpose. The study aims to develop and experimentally verify the model of functional literacy development of junior schoolchildren based on digital educational resources. Methodology. The study employed analysis, comparison, systematisation, classification, generalisation, experiment, and methods of mathematical statistics. Results. The concepts of �functional literacy�, �development of functional literacy of junior schoolchildren�, and �development of functional literacy based on digital educational resources� were defined. The research was conducted in general education schools �School-lyceum No. 66� and �School No. 16� (Karaganda).
