Do you remember this game?
It is now available as an iPhone App. You can play either the original or the updated version. I was playing it with my year five and six classes during planning week. I offered a Mars Bar as a prize for the person, or team, who made the most money in 30 days. We had only a limited number of iPads available so some students worked by themselves whilst others played in pairs. In class after class the pairs won. I think, in these days of 1:1 learning, it’s very easy to forget how much more effectively some children learn when working with others.
