If your lesson is only 45 or 50 minutes, you might often complete much less than was planned.
Teachers want their lessons to be vibrant and useful but time flies so quickly that at the end of the lesson they feel frustrated. So much time was wasted on a “proper” warm-up and homework analysis. If you feel this way, consider one-minute warm-up activities to save time for other significant tasks. The activities in the article can be adapted to levels from A2 to C1.
Guess the topic of the lesson
It’s one of the quickest and easiest ways to lead in almost any topic, to engage learners and to maintain mini-discussion. You can show one picture or make a collage, demonstrate it and make students guess what the lesson is going to be about.
For example, the topic is ‘Artificial intelligence’.
