Brainstorm. This game is pretty appreciated by kids in classes.
First the teacher writes on the chalkboard all the colors the students know and say, for example.
Also pretty soon you will get the board covered by colors, or means of transportation, or...
Then a volunteer – they all want to be him – stands up and turns around, his back to the board. And he says all the colors he can remember from the chalkboard. The rest of the class-group are with wide open eyes and in tension.
Finally some student can say out a missing color by the volunteer. Amazing and amusing. / Photo from: brainstorm www eslflow com
