The flags of Western Europe matching was designed to be part of a unit of study on Western Europe. In my Montessori classroom we do monthly themes on different continents and regions of the world. I made this flag matching to go with my unit of study on Western Europe.
When using this work I print two copies of the paper. One copy of the paper is the control sheet and the flags on the other copy are cut apart and matched to the correct flag on the control sheet.
The Tinkering Shop has several other Western Europe related materials to make up a unit on Western Europe.
