An A-Z quiz of 52 questions based on the letters of the Alphabet. It could be used for one class of 26 questions. The students will write A-Z on a piece of paper and the teacher will read the questions. After the students have finished have them write their name on the piece of paper and swap with another students to mark their score when the teacher reads the answers at the end.
This is a fun activity that will take up the most part of one whole class. Even advanced classes may struggle with some of the answers.
