A thirty minute quiz activity for testing subject knowledge, encouraging discussion, and generating enthusiasm in any classroom. Hardly any teacher preparation is required. This quiz format can be used for any subject. The teacher makes a list of 20 questions on the topic pupils are working on. These can be delivered orally or typed onto the on screen blackboard. There is an optional one minute timer (with sound effects) to focus thinking. Pupils are divided into four mixed ability teams, with one pupil white board per team for writing answers. Scores for correct answers are added to the on screen display. (They can also be deducted if necessary. NOTE: You need to ensure that macros are enabled on your computer in order for the on screen blackboard to work. A security warning will appear when you load the file asking if you want to enable content.
