It's Christmas time. Today I had my last lessons before Christmas break. I've prepared a surprise for my younger learners. I've made a large picture sudoku board (60 cm x 60 cm) to teach them Christmas vocabulary (Santa, reindeer, present, sledge).
At first we did the puzzle together, so they could get an idea what sudoku is. Then I devided them into small groups of three and they solved more advanced puzzles with the same pictures.
Here's a printable that you can use with your students.
