Multibase (Material Dourado)

This application, deployed for Android devices by José Alexandre Macedo, was created by Ron CO Freitas, from his master's research entitled "An Environment for Virtual Operations with Gold Material", defended in 2004. It is a virtualization material developed by Italian educator Maria Montessori, used to teach concepts of number and arithmetic operations. The intention is to complement practices made with concrete materials in the early grades of elementary school offering another option for handling on several bases.
