Reflection: Connection to Prior Knowledge Volume of Composite Shapes - Section 2: Opening


When my students saw the first page of this lesson they smelled a rat.  They said "we've done this lesson before!"  I asked them to tell me the objective:  SWBAT solve problems involving the volume of composite shapes.  The first page looks just like the surface area of composite shapes page; only the questions have changed to reflect volume.  

After explaining to my students how it saved me time searching for more composite images we got down to work.  

Next time I present this lesson, I will remove the 6 question that guide the students to making sense of the problem.  I will just present the shapes and ask them to explain how they would find the volume.
