Keeping secondary students engaged in a lesson can be challenging at times. I have found that card sorts help to keep them motivated and interested plus it provides a quick overview of their understanding.
Card Sorts are a great way to incorporate group work into your lessons. It can get your students moving around, especially if you use them as a treasure hunt activity.
It can help less confident students to give their opinion in a small group. They will be more likely to move a card around on the table than raise their hand in class to answer a question.
