Secret Spreadsheet v1.0

Our first public release of Secret Spreadsheet!

This Materia Widget tasks students with filling in the blank cells in a pre-populated spreadsheet. As the author of a Spreadsheet widget, you can choose to selectively hide individual cells or ask the widget to randomly select a number of cells to hide each time. Students are assessed based on the number of cells they guess correctly and are given immediate feedback about which cells they missed upon completion.
