Set the learning objective before writing the first question
A quiz can be used to activate prior knowledge at the start of a lesson, check understanding partway through a concept or review before a test. These three purposes don’t call for the same questions or the same pace. Write down in one sentence what students should be able to do by the end of the quiz.
This objective acts as a filter: any question that doesn’t help you check it can be cut. It’s the surest way to avoid overly long quizzes, which tire the class out and dilute the information that’s actually useful to the teacher.
Also decide where the quiz fits in the unit. At the start, it brings out what students already know and can spark curiosity. After an explanation, it checks that the message got across. At the end of the unit, it prepares students for the test and reassures them about what they’ve mastered.

Write questions that make students think
The quality of a quiz depends above all on its wrong answers. Plausible distractors, built from mistakes actually observed in class, reveal misconceptions far better than far-fetched options.
- One idea per question, worded without double negatives
- Distractors based on common student mistakes
- Answers of similar length so none gives a clue
- A few application questions, not just recall
- A more open-ended question at the end of the quiz to spark discussion
Create and run quizzes with instant feedback, turning assessment into a learning activity.
Explore the solutionChoose the right format and length for your class
For a quick check in the middle of a lesson, five to eight questions are usually enough. For a review session, a longer quiz divided into topics lets you pause and revisit weak spots. Adjust the response time to the difficulty: a calculation or analysis question deserves more time than a vocabulary question.
A tool for creating questions quickly, such as QuizPlay, lets you prepare these variations without spending your whole evening on them and reuse questions from one unit to the next.
Running the quiz in class without losing the thread
Whole-class facilitation works when the quiz is punctuated by short explanation breaks. After a question where answers are split, ask one student to justify their choice, then another to defend the opposite answer. This moment of debate is often more instructive than the correction itself.
Also pay attention to the classroom climate. If the competitive element puts some students on the spot, opt for anonymous answers or team answers. The goal is for everyone to feel comfortable answering, even when they aren’t sure.
If some of the class is joining remotely, explain the rules before you start: how to join, how much time there is to answer, how to ask a question during the debrief. Read the questions aloud so no one is disadvantaged by a hard-to-read display, and call on remote students by name during the explanations.
Using the results for the rest of the unit
Instant results aren’t just for congratulating the top performers. Look for questions most of the class got wrong: they point to a concept that needs revisiting, or sometimes to instructions that were misunderstood. Also note the most frequently chosen wrong answers, since they pinpoint the exact misconception to correct.
Then reuse the missed questions a few days later in a slightly different form. This spaced repetition reinforces learning and lets you check that the review paid off.
FAQ
How many questions should a classroom quiz have?
It all depends on your objective and the time available, but a short quiz is almost always more effective. For a check during a lesson, a few well-chosen questions are enough. It’s better to save time for discussing the answers than to rush from one question to the next.
Should interactive quiz results be graded?
For formative assessment, it’s better not to grade them. Students answer more honestly when they know mistakes are allowed, which makes the results more useful to the teacher. Grades can be reserved for other forms of assessment.
What if not all students have a device?
The quiz can be played in teams, with one device per group, which also encourages discussion before answering. You can also project the questions and collect answers by a show of hands or on mini whiteboards. What matters is preserving thinking time and the debrief.
