    Practices in this Lesson

    Math
    MP.4

    Model with mathematics

    (Also available in WeScheme)

    Students define the shapes used to build a rectangular prism, print them, cut them out, and build the rectangular prism. Then they use their model to calculate the surface area.

    Lesson Goals

    Students will be able to:

    • Demonstrate understanding of surface area and use that understanding to calculate surface area of rectangular prisms

    Student-facing Goals

    • I can explain what surface area is.

    • I can use my understanding of surface area to calculate the surface area of any rectangular prism.

    Materials

    Preparation

    • This lesson requires a printer, scissors and tape.

    • Decide whether students will be printing in black & white or in color.

    • If you’re printing in black & white, colored pencils may be useful for some students.

    Key Points For The Facilitator

    • This lesson focuses on developing students' understanding of Surface Area of prisms, such that they can build their own formulas. Instructors are encouraged not to reference any pre-defined formulas during the exploration.
    Glossary
    dimension

    a measurement of something in a particular direction, especially height, length, or width. The dimensions of a computer screen, for example, are given as width x height.

    face

    the flat surfaces on the outside of a solid figure

    rectangular prism

    a solid figure which has 6 faces, all of which are rectangular

    surface area

    the sum of the areas of all of the faces of a solid figure (polyhedron) or the total area that the surface of the object occupies

    🔗Surface Area

    Overview

    Students build on their experience with writing code to define shapes. They will define shapes for all of the faces of a rectangular prism, print them, cut them out, and build the rectangular prism. Then they will use their model to calculate the surface area and write code to do the same.

    Launch

    Invite students to share out to gauge their prior knowledge of surface area.

    Be sure that students notice that the faces and dimensions (length, width, and height) are labeled. Invite them to observe how many faces there are, as well as how many differently sized faces there are. Students who clearly see that there are three sizes of faces, with two faces in each size, will be able to move more confidently through the remainder of the activity.

    Faces are the flat surfaces on the outside of a solid figure. Edges are the line segments where the faces meet in each of the three dimensions. The surface area of a prism is calculated by adding the areas of its faces.

    • Go to PART 1 and look at the definitions for front and back. Type front into the Interactions Area. What do you get?

      • A black-outlined rectangle that has a width of 180 and a height of 50.

    • The faces front and back have been defined to draw a rectangle whose dimensions are width and height. You will need to write definitions for each of the other faces of the prism.

    • Click "Run" and test each of the faces in the Interactions Area to make sure that they match the prism you started with.

    Facilitation Note The sample definitions were written to make images of outlined rectangles with a black and white printer in mind. If you have access to a color printer in your classroom, you may want students to change the code of front and back to better match what they see in the image of prism and code the remaining faces with solid rectangles to match the image they are looking at. If you do not have access to a color printer, but think that colors would support your students, you can have them color the rectangles on the printout before cutting and assembling the prism.

    If you do not have a classroom printer, consider splitting this lesson over two days - the Launch segment on Day 1, and the Investigate and Synthesize segments on Day 2. At the end of Day 1, direct students to share their images with you. Print the images and distribute them before beginning the Investigate segment on Day 2.

    • Go to PART 2 in the code. Type print-imgs​(​faces​) into the Interactions Area. How many rectangles do you see?

      • Two.

    • The code in PART 2 says faces = list​(​front, back​) , which defines faces to be a list of values. This list will include all of the faces of the prism, but right now it only includes front and back. Add the names of each of the remaining faces to the list. (Order doesn’t matter - but be sure to put commas in between list items, and do not use the word “and”.)

    Ensure that students' lists include all six faces of the rectangular prism.

    • When you’ve finished, click "Run" and again type print-imgs​(​faces​). What do you Notice? What do you Wonder?

    • Do you have enough shapes to cover all of the faces of the prism?

    • Read the comments in PART 3 of the file to learn how to print the faces to build your prism.

    Investigate

    Have students cut out and tape together the images they defined to form a 3-dimensional paper model of a rectangular prism. Students will then use their models to calculate the surface area.

    Supporting students with learning variations

    • Labeling the shapes with face names and/or area before taping them together may help some students.

    • Printing two copies of the file (one to cut and one to write on) might best support other students.

    Synthesize

    Have students share the code they wrote to define surface-area. Did students all write the code the same way?

    Three possible correct ways to define surface area are:

    • surface-area = A-front + A-back + A-left + A-right + A-top + A-bottom

    • surface-area = (2 * A-front) + (2 * A-left) + (2 * A-top)

    • surface-area = 2 (A-front + A-left + A-top)

    For further debriefing, discuss the following:

    • How did building the prism help you to understand surface area?

    • How did writing the code for surface area help you to understand surface area?
