This is an information-gap activity where the children work in pairs. Both receive a box for the burger (bought or made oneself) with imprint on the outside and a list of ingredients on the inside in the top as well as all ingredients laminated. Both children put the lower half of the burger bun in the box. The auxiliary shields are put between the children. The customer puts all the ingredients he or she would like to eat on his or her burger in the box. After that, the cook asks the customer what he or she may put on the burger. In the end, both compare their burger and check if they are alike.
