SWBAT solve problems involving the volume of composite shapes

Composite shapes are everywhere in the real world.

I will now have students turn to the first page of the module (packet). I will given them a few minutes to quietly and independently fill out the 6 questions on the page. These questions mirror the questions from the previous section. I will check students answer as a check for understanding while they are working. We will quickly go over the answers. If there are any general misunderstandings we will highlight those and discuss.

I will allow students to work with their partners on the problem solving tasks. Problems 1 and 3 are almost identical to the problems we looked at in the previous two parts of the lesson. I included a cylinder with a hole in the shape of a cone. I provided a formula in this case since we will not work with cones until 8^{th} grade.

If time is limited, I will try to make sure all students do 1-4 and then perhaps pick an option for 5-8. I’d like everyone to have a chance to get to the extension. This problem develops MP1 as the task involves making sense of the LEGO dimensions as given. It also develops **MP7** as students match the 2D and 3D representations of the LEGOs to understand the dimesions.

I have provided 3 questions. The first two involve the same skill (only the component shapes differ), so I may tell students to pick either 1 or 2 and then have everybody do 3.
