An intervention was planned for this purpose and two large-scale giant maps with dimensions of 3 × 4 m were created, a map of the city of Mytilene with a scale of 1:1000, and a map of Lesvos Island with a scale of 1:20,000. The sample was 56 kindergarten pupilsKindergarten pupils (28 boys and 28 girls) aged 4 to 6 years old. Children’s knowledge and abilities were tested using a questionnaire before and after the intervention, with the help of kindergarten teachers who wrote the answers as children of this age do not know how to read and write.
