Maybe the site formerly known as Twitter is circling the drain, but I’m still getting some wonderful resources from it. Case in point is a recent thread started by @kathyhen_ where she asked for more ideas for fast finishers in her class. She helpfully provided a doc that she gives her students, and then many people responded with additional suggestions.
#mtbos #iteachmath folks – I have a list of mathy/wordy game sites that I allow my students to go to if they finish a lesson early. I feel like I'm missing some. What am I missing?https://t.co/WpzhdBKGU8

Though many of the sites are already part of my Math Sites That Won’t Make You Fall Asleep and Brainteasers and Puzzles collections, I did see a few that I need to add. One of those is called, Sumplete.
To play Sumplete, you simply click on numbers in each column and row to “X” them out so that they will actually add up to the sums on the right and bottom of the grid. In the example above, 19 is bolded, which means that row already adds up to it, so you don’t need to delete any numbers. However, the middle row needs a number deleted so that it will correctly add up to 16. I can click on the 5, but I need to make sure the 5’s column will then also equal 10 when it’s deleted, as it does.
The Sumplete page gives more detailed instructions if needed. As you can also see in the above example, there is an arrow next to 3×3, which you can click on to select larger puzzle grids. Once you get to 6×6, you can also choose the difficult level. The most difficult is 9×9 master.
Interestingly, the Sumplete page mentions that the puzzle was created in collaboration with ChatGPT, and you can read all about the steps the creator, Daniel Tait of Hey, Good Game, went through for this process. It inspires me to try my own puzzle creation, so I’ll let you know how that goes 😉
