I just love this activity from Andy Milne:
One way to use it is to simply "make a copy for each student" via Google Classroom, give your students a length of time for the challenge to occur and off they go! You could award some type of small reward for a bingo, or just make a bulletin board to highlight those who get a bingo. Perhaps create another space for those who cover the whole board. You could easily make this a whole school class-by-class challenge too!
The file is easily editable to meet your needs. Make a copy of it and off you go!
