Prepare the game by writing down a list of "Yes- or No questions".
Divide the children into two rows and place a chair a few meters in front of each row. On one of the chairs there is a note saying "Yes" and on the other there is a note saying "No".
Ask a question from your list. The first person in each team/row runs towards the chairs and sits down on the "Yes" or the "No", depending on what he/she thinks the correct answer to the question is. The person who sits down first on the correct answer gets a point for his/her team. The team with the most points in the end wins!
