This is a mystery grid on Google Sheets that features Mario from Super Mario World. The students will solve the problems and as they do the grid will start to fill in the colors for the picture. I have left the answers on the grid but you only have to erase those before sharing the file with your students and they will be ready to go.
Disclaimers: There are no commas in the answers just the digits to the answer. This is a digital item through Google Sheets and Google Drive.
