For this game you have to divide your students into two lines. Then you call out something that they have to write on the blackboard ( you can say a letter of the alphabet, a word, a verb, the past of a verb or even ask them to draw a picture!).
The first person of the line runs to the blackboard and writes the word. The first person to finish gets a point for their team and go to the back of the line.
This is a great game where you can practice any type of vocabulary or grammar (you can ask them to write a sentence) and is suitable for any age, since you can adjust the difficulty.
