This study reflects how students lack the fundamentals of Math and the algorithmic thinking required to solve the problems established in the educational digital material. The results show that doing a reiterative challenge help students not just to get the fundamentals of Math, but also to solve the algorithms used in the educational digital material, learning from the mistakes made.esAlgorithmscomputational thinkingcritical thinkingeducational digital materialInformation and communication technologiesArticle
