  • It is very important that teachers insist on a step by step procedure as follows:
  • 1 TMB
  • 2 LCR + ram
  • 3 Fill in any empty cell in a row, column or block
  • ram (ramifications) whenever you solve a new number ALWAYS LOOK RIGHT OR LEFT OR UP OR DOWN TO SEE IF BY USING TMB AND LCR A NEW NUMBER CAN BE SOLVED. It is easy to miss a ramification. A good habit to master
  • puzzles for students are provided to solve, along with suggestions for teachers.
  • students learn the importance of mastering procedures that make them successful puzzle solvers
  • watching the videos is fun
  • help students look at 3 horizontal blocks and spot where a number is missing in 1 of the 3 blocks using TMB Robin the Sudoku guy will show how this is done in the video
  • help students look at 3 vertical blocks and spot where a number is missing in 1 of the 3 blocks using LCR. Robin the Sudoku guy will show how this is done in the video
