Worksheets, textbooks, internet, exercise books, each other or none!
What to do:
In preparation for the task each student should be given a certain amount of time to prepare notes and gather knowledge about their chosen/assigned topic.
You should then set half the students up as market stall owners. Standing up behind a desk. (With or without notes.)
The other half need to visit the market stalls and ask questions about the stall owners topic. They should then fill in their answer booklet/take notes based on the answers.
Repeat this process, swapping the students roles over.
Or the shoppers may only buy answers by offering answers on their topic too.
Variations:
Students to work in groups initially gathering knowledge. They would then take it in turns to visit other groups to gather information. Coming back to then reteach it to their group members.
