Reflection: Modeling Finding the Surface Area of a Triangular Prism Using A Formula - Section 1: Lesson Beginning

 

This is another direct instruction that reflects how teachers at my school have been encouraged to teach over the past several years.  This model has served us well but over the years but we have realized that the rigor of the common core will require students to do much more of the thinking.  This is opposed to the "do what I show you" method of a direct instruction lesson.  

In light of this, the examples may not be modeled by the teacher at the onset.  First we will go through the 6 discussion questions above the example.  This discussion should help most students find the surface area of the triangular prism in the example without it first being modeled by me.  

This approach has served me pretty well as I start to transition away from so many direct instruction lessons.

Finding the Surface Area of a Triangular Prism Using A Formula

Unit 6: Geometry
Lesson 19 of 37

Objective: SWBAT find the surface area of triangular prisms using a formula

Big Idea: Students learn a more efficient method for finding surface areas other than using nets.
