O Círculo da Matemática do Brasil


About the methodology

The Circle of Mathematics in Brazil methodology is the adaptation, to the Brazilian setting, of The Math Circle approach, developed by Harvard University professors Bob and Ellen Kaplan. In it, errors, conjectures, examples and counterexamples given by children are key ingredients in pondering and reasoning of thought and lead to the creation and appropriation of math knowledge with confidence. The approach core idea is “tell me and I’ll forget it, ask me and I’ll find out”.
