INTERMEDIATE+PERFORMANCE+-+TRIANGLES

In pairs, students construct with ruler and compass different types of triangles, to be included in the external view blue print of their structures. They are required to classify each triangle according to their sides and angles and compare them with other geometric shapes, by analyzing their properties. To do this: 1. After watching a power point presentation about civil structures, students participate on a hands on activity, in which they are divided in 3 groups and each group construct different types of polygons with manipulatives. When the different types of polygons are constructed they are tested for rigidity and students find out why triangles are preferred for constructions.

2. According to their learning styles, they watch or read 6 tutorials about how to construct triangles and they begin their constructions by picking 3 options from a tic tac toe. 3. They justify in a paragraph the location of these triangles in their structure's blue print. media type="custom" key="12439544"
