Write the numbers 1 to 10 on the snake.
Ensure that number 10 is always at the head end and number 1 at the tail end.
By placing two number snakes underneath each other the columns all add to eleven. By placing three number snakes underneath each other the columns add to: 12, 13, 14, 15, 16, 17, 18, 19, 20 and 21. What would happen if students added a fourth column? Experiment and have fun!
