正在進行的數獨謎題

Class Content: 
     ~Each week students will spend time working on solving a large Sudoku game. The game traditionally uses numbers. We will be playing using a variety. Some games will be played with numbers, letters, and pictures. The object of the game is the same, we will just be challenging our minds a little more in some games. 

Class Structure and Teaching:
      ~ At the start of class I will take attendance and go over the rules for the game and class. 
               - How To Play:
                      ~Each row across must have 1 of each symbol
                      ~Each Column up and down must have 1 of each symbol
                      ~Each darker square must have 1 of each symbol
                      ~Only the colored tiles may be moved
                - Class Rules
                      ~ Be respectful to other classmates
                      ~ Pay attention and don't interrupt classmates.
                      ~ When collaborating with a classmate while someone is speaking use the chat feature in zoom.
       ~ Students will volunteer to give an answer to a square of their choosing. If the same people are answering and volunteering all the time I will call on a student to give their opinion and thoughts to help other students. If they don't know I will help them and work with them to answer the question so they don't feel embarrassed. This class is meant to be fun and stimulating to the mind. 

       ~ When we have about 3 minutes left of class I will give the warning that we need to start wrapping up. If the puzzle is not finished we will continue the following week. If the puzzle is finished we will start a new puzzle. Students can join the class at any time. An updated copy of the puzzle will be posted each week so it will be like a brand new puzzle to those who are joining new.
