Centroid and Orthocenter

Tenth graders explore triangles.  In this geometry lesson, 10th graders construct the medians and altitudes of a triangle and investigate the properties of the centroid and the orthocenter.  The use of dynamic geometry software allows students to manipulate the constructions as they make and test conjectures.

Hi, I was recently hired as a middle school science teacher in Newark, NJ. I received a call on a Friday and was asked to begin the following Monday. As a new teacher, and with only 3 days to prepare, I was really feeling the pressure. The school requires 2 weeks of lesson plans every Sunday, so I began searching the web for help. Thank goodness I found Lesson Planet. I still use the site everyday to form great lessons and activities for the kids.
