The lesson focuses on attainment of procedural knowledge and conceptual understanding, related to surface area and volume. Students will:

- draw nets from rectangular prisms, in order to solve surface area problems.
- calculate the surface area and volume of rectangular prisms and cubes.
- solve real-world problems, involving surface area and volume, using a variety of problem-solving strategies.

- How can recognizing repetition or regularity assist in solving problems more efficiently?
- How are spatial relationships, including shape and dimension, used to draw, construct, model, and represent real-world situations or solve problems?
- How can the application of the attributes of geometric shapes support mathematical reasoning and problem solving?
- How can geometric properties and theorems be used to describe, model, and analyze situations?

**Congruent Figures:**Figures that have the same size and shape. Congruent angles have the same measure; congruent segments have the same length.**Cylinder:**A solid that has two parallel, congruent bases (usually circular) connected with a curved side.**Net:**A two-dimensional shape that can be folded to create a three-dimensional figure.**Prism:**A three-dimensional solid that has two congruent and parallel faces that are polygons. The remaining faces are rectangles. Prisms are named by their bases.**Surface Area:**The sum of the areas of all of the faces of a three-dimensional figure.**Volume:**The amount of space found within a solid.
