Ten different activities deal with perimeter, surface and volume.

• questions about the perimeter and the area of shapes;
• calculate the perimeter or the area of various shapes;
• construct a shape with a specified perimeter and/or surface;
• count the number of missing blocks in a cube;
• calculate the surface of two geometric shapes and search the ratio between both;
• calculate the surface of circle sectors and regular polygons;
• calculate the volume of a cube, a bar, a cylinder or a prism;
• identify the requested shapes;
• indicate the correct shapes given a number of properties;
• solve mathematical problems;
• evaluate questions and/or statements.
