Ada Lovelace’s life is a source of inspiration for women and men of all ages, for being a bright-minded and visionary person. His greatest achievement was to have written the first computer program in history. This article presents a methodological proposal for didactic use of a children’s book about Ada Lovelace by proposing a circuit of unplugged activities in order to refine the computational thinking (CT) in children and adolescents. This methodology was applied in a workshop during the BLIND in the BLIND Conference. A quali-quantitative analysis performed with participants indicates the suitability of the proposed methodology.
