Thanksgiving Arithmagons

The first Thanksgiving was celebrated in 1621 over three days. There is no record of turkey being eaten at the first Thanksgiving but other foods were eaten such as seal, lobster and swan! Today over 46 million turkeys will be eaten!

The aim of an arithmagon is to work out which numbers go in the empty circles. The numbers in the square boxes are made by adding together the numbers in the circles either side.
