Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
Divide players into teams, depending on the number of students you have. Ask them to think about the future and what they wish to have then... they will be the inventors! Ask them to give name to his invention, and to make an accurate and interesting description... and above all, do not forget the price! Once the task, get them to expose to their classmates.
