The teacher prepares two series of numbers from 0 to 9 in A4 each digit, and gives one number to each pupil.
Teacher starts asking the named pupil to step in front of the blackboard showing to the rest of the class the number given. The teacher writes on the board at the head of each pupil the corresponding order: units, tens, hundreds, etc. We all name the number.
Then the teacher asks which pupils will have to change position if I add 2 tens, or I want the number 3.456, or change the thousands for the units. Children have to think the operation, the answer, and the children that would have to change position.
In every change, we say the new number.
