  Kids have an amazing capacity to use modern electronic devices such as
tablets, smartphones, etc. This has been incredibly boosted by the ease of
access of these devices given the expansion of such devices through the world,
reaching even third world countries. Also, it is well known that children tend
to have difficulty learning some subjects at pre-school. We as a society focus
extensively on alphabetization, but in the end, children end up having
differences in another essential area: Mathematics. With this work, we create
the basis for an intuitive application that could join the fact that children
have a lot of ease when using such technological applications, trying to shrink
the gap between a fun and enjoyable activity with something that will improve
the children knowledge and ability to understand concepts when in a low age, by
using a novel convolutional neural network to achieve so, named FINNger.
