The class is arranged into rows. The first person in each row is given a piece of chalk. The blackboard is divided into sections. No more than six teams.
The teacher calls a letter and the students must write as many words as they can beginning with that letter, in the allocated time. Their team-mates can call out hints, but be warned, this is very noisy.
Next, the second member gets the chalk and goes to the board and the teacher calls out a new letter.
The team with the most correct words is the winner
