Day+2+Group+Work

__Day 2 Group Work__

We had a total of eight students split into two groups--one group developed the user interface using the app inventor designer and the other group developed the code for doing fraction arithmetic and reducing a fraction using the app inventor blocks editor. There is no way to collaborate at the moment other than sharing the project back and forth but that worked okay for a project this size with two groups.

The following is a blocks-editor procedure to find the GCF (the euclidean algorithm) between the numerator and denominator in order to reduce the fraction to lowest possible terms:



The following is a block-editor diagram for the add_button_click event. More code needs to be added to do error checking for bad input.
