I don’t know about you but when you believe that an assessment will take a whole period and for some reason it does not it strikes a little panic in my heart. I mean, if students aren’t engaged bell-to-bell I feel like I’ve not done my job (even if they think that this is an ok thing to happen). Also, I don’t want students to speed through things so that they can have down time at the end. To battle this I sometimes use the following game. You can make them up easily on the fly. I’ll call it Sum Sudoku. I’m pretty sure I stole it from somewhere – I wish that I could give credit where it is due.
Here is how it works:
1.) Start with a 3×3 grid
2.) Fill it in with the numbers 1-9 (no repeats, any order)
3.) Write the sum of each column, row and the diagonal next to a clear 9×9 grid.
4.) Fill in a couple of choice numbers
5.) Have students figure out where the remaining numbers have to go
I usually take three “winners” and make a new one while students are working on one.
To make this post I created an Excel file to create this particular puzzle.
