My year 13 class were ready to practice finding points of intersections of two curves using their calculators. Instead of a boring textbook exercise, I made this treasure hunt for them.
There are ten orange cards stuck to the walls, windows, chairs, and surfaces of my classroom. Each one has a question. Students travel around the room in pairs, solving the questions. Then they look for the answer on another card.
The students know they have finished when they have visited all ten cards and solved ten problems. They need to tell me the card numbers of the loop they followed, which allows me to check their work.
Treasure hunts are easy to make and are a clever way of turning a worksheet or textbook exercise into a more social exercise that students enjoy. The cards are available here as a document and as a pdf.
