Part of something bigger? Children's interactive exhibitions

The recognition of the need for practical, hands-on experience in learning mathematics is not new. The project It was ideas like these that shaped Mathematics in the Making(MiMa) (MiMa, 2015a), a European Union (EU) project (http://www.mathematicsinthemaking.eu), (Project no. 539872-LLP-1-2013-1-IT-COMENIUSCMP) funded through the Comenius Lifelong Learning Programme, which was based on a primary school mathematics intervention in five EU countries - England, Germany, Hungary, Italy and Portugal. Project teachers worked on the mathematics of the activities through professional development workshops. The physical models and activities produced in the project represented the concrete output of the children's mathematical thinking and acted as a supportive bridge to their reasoning and explanations.
