Introduce Key Concepts and Vocabulary

  1. Introduce students to midsegments and theorems. Allow students to find the parallel side and the lengths of the midsegment as well as the third side when asked. 
  2. Introduce students to the median of a triangle and show that all the medians of a triangle intersect at the centroid. Introduce centroid properties with respect to distance. Have students experiment with the median and finding lengths.  
  3. Show students how to identify the altitude of a triangle and how to identify altitudes given multiple triangles. Introduce and have the students identify the orthocenter.

Tips and Tools

Have students enter their observations (what they learned, what they need to learn, etc) in their Daily Learning Logs
