When I was looking for great links to include in my September Wakelet, I discovered that September 9th is International Sudoku Day. Of course, I can’t ignore that because I literally play Sudoku every single day. It’s my favorite “down-time” activity. I put several links in the Wakelet to help you celebrate this auspicious day, including some online Sudoku games and some places you can find free printables. There’s even a link to a free picture Sudoku you can download from TPT. And, don’t forget to check out the interactive Sudoku bulletin board ideas that you can find here.
I used to like using Jigsawdoku with my students because it allows you to choose different options in order to scaffold. For students who need some extra challenge, you can have them try Mystery Grid (click on question mark for instructions) or Inkies (also known as Ken-Ken Puzzles or Mathdoku). And if you have some students who get really passionate, you can try one of these alternatives.
