I strongly believe students are born with a knack for creating, tinkering and hacking. Unfortunately, the traditional model of learning is driven by consumption and regurgitation of information. Why not have students create something that not only demonstrates their understanding, but also creates a challenge for their peers to solve?
Students are exploring coordinates in math. In an effort to allow students an opportunity to showcase their understanding of coordinates, I thought of Alice Keeler's Pixel Art Google Sheet Template. Her template uses conditional formatting to change cell colors.
This got me thinking about the idea of a hidden picture that would be revealed if coordinates were successfully marked. The picture below represents the hidden smiley face that I created. I numbered the cells in column A from 20 back to 0. The cells in row 21 are numbered from 0 up to 20. A key of coordinate pairs is provided for students to type an "x" which in turn changes the specified cell to the color black. If done correctly, the hidden picture will be revealed.
