In this lesson, students build on their experiences with perpendicular bisectors by creating Voronoi (vo-ro-NOY) diagrams to answer questions about allocating resources in a real-world situation (MP4). There are two optional activities that both provide the opportunity to apply another Voronoi diagram. One focuses on additional aspects of the mathematical modeling cycle, while the other introduces tessellations.

Some of the activities in this lesson work best when each student has access to the GeoGebra Geometry Tool from Math Tools or at https://im612.org/geometry-tool. Using the GeoGebra Geometry Tool rather than the GeoGebra Constructions Tool gives students access to a perpendicular bisector tool.

Math Community

Today’s community building centers on the teacher sharing their draft commitments as part of the mathematical community. At the end of the lesson, students are invited to suggest additions to the teacher sections of the chart.
