If you have not used Google sheets before, if you look at the bottom of the page you will see there are two sheets included. They are the Teacher Key, and  the student copy. When you are ready to assign it to your students, make a second copy of the Google sheets and go to the bottom of the page where it says key and right click on that page. When it shows options, click on delete the teacher key before assigning and sharing with the students. They should only have the student copy. The mystery pixel picture will appear as they fill in column B with correct answers. Directions are included on the student worksheet. This works best if they zoom in and out at 50-90%. Students also need to spell the words correctly for the correct answer to work. I have included this in their directions. Hope you and your students enjoy the activity!
