Puzzle sunday (8)

Because I'm busy to find a house in a certain region, I use maps a lot these days. So I link a map puzzle today. This jigsaw has countries as pieces of the puzzle.

Puzzle Sunday (7)

This week was the international mathematics competition in the Netherlands to which 4 million children worldwide participate. The name for this competition is the Kangaroo. On this map you can see what countries participate. For this occasion I thought maths puzzles would be in order. Many, many maths puzzles.
