## Objective

SWBAT create a response to an open-ended question using the application of surface area.

#### Big Idea

How much paper do you need?

## Launch

5 minutes
• POD

As students enter the room, they will have a seat, take out their Problem of the Day (POD) sheet and begin to work on the question on the SMARTboard. The POD allows students to use MP 3 continually based on the discussions we have about the problem each day.

The POD today will be a simple question to bring the idea of solving a problem on finding the surface area of a rectangular prism to the forefront in their minds.  I want students to effectively describe what needs to be covered (in terms of the faces of the prism) and how to find those dimensions. When they work to answer the actual Write It Wednesday question, I want them to know how to find the answer conceptually and just focus on preparing a solid, complete answer.

How would you measure the amount of paper needed to cover a box?

3. Receive a classmate’s paper to critique and provide feedback
