Students are in teams. Each team member is given a vocabulary item - eg a color. There is one of each colour in each team. Either tell each person their colour, or give them a card with that colour.
Students merely point to the item that the teacher says.
Allow students to look at their friends' responses for this. This can be used for the presentation stage of the lesson, but needs to be kept brief. It can also be used to review items prior to a speaking activity in games such as Snakes and Ladders and Follow the Wire. Perhaps it is easier to learn from fellow students rather than from the teacher. Listen, Look and Do.
