In the movie Concursante, there is a scene about trade and value of different things.

Mathematical theme:    1. equations
                       2. two equations with two unknowns

  1. Play with the items on the templates.
  2. Built equations for each other - rotate among the teams - we will guide you.
  3. Use Geogebra and draw the equations there to solve the problems.
  4. Show each other how you work with equations in your respective countries using pen and paper.
  5. Make up a story and make a short video where you demonstrate how equations are necessary in trade.
Products of the soil - exchange of goodies - but these could not last - rot away.
