The problematic situation in this case involves a comparison between the prices of different popcorn packaging sizes in Bauru ́s movie theaters and its area. / Este trabalho apresenta uma sequência didática para aulas de Geometria abordando o conceito de semelhança com foco na variação da razão de semelhança entre medidas lineares e medidas de áreas e de volumes de alguns poliedros, tendo como situação problema a comparação de preços de diversos tamanhos de embalagens de pipocas vendidas em salas de cinema da região de Bauru.
