A primary teacher's explanation of MMP. There's one mince and cheese pie left in the shop. It costs $5. Bill has $4.50, Jacinda has $3.70, Winston has 70c, James has 60c and David has 5c.

No one has enough money to buy the pie themselves but Jacinda, Winston and James put their money together to buy the pie. Bill gets no pie because he needs 50c, but didn't have any friends to help him buy the pie.

This is exactly what MMP is all about.
