Incredible Edible Bridges
Learners create a bridge using engineering and geometric concepts. In this geometry lesson, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using problem solving...
Illustrative Mathematics
Tangent to a Circle From a Point
Learners see application of construction techniques in a short but sophisticated problem. Combining the properties of inscribed triangles with tangent lines and radii makes a nice bridge between units, a way of using...

Building With Triangles
Fourth graders use two different techniques to construct triangles with specific dimensions. They determine how to construct nets for three-dimensional objects focusing on those made with equilateral triangles. They are able to name the...
Inside Mathematics
Hexagons
Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.
