The activity was explained and both teachers dramatized it. Once the children knew what to do they were given a number which they had to stick on their sweat shirt.
The idea of this game is for each child to walk around the classroom asking: Do you have number 11? So the child who has that number writes his or her name on the child´s paper and so forth until the child has completed asking about all the numbers.
Whales play Cooperative games quite often and learn and go over numbers in a different way. They had great fun, moved around the classroom and worked with the numbers they had!
