Learning Target (s)
- I can draw the "net" for a rectangular prism, triangular prism, and cylinder.
- I can calculate the surface area of a rectangular prism
- I can calculate the surface area of a triangular prism
- I can calculate the surface area of a cylinder
In Class:
Introduced vocabulary:
Net- a 2-D drawing of a solid figure- what a 3-D object looks like when cut apart & "flattened"
Looked at "real life" examples of "nets" to determine the shapes of faces of 3-D figures
Examples: "cut apart" Pringles can (cylinder), Mac & Cheese box, Toblerone Candy box
Notes:
Students took notes on graph paper. Students created nets and calculated surface areas for: rectangular prism, triangular prism and cylinder.
Homework:
page 541 problems 7-10
- Draw the "net" of each figure
- Calculate the surface area/ show all steps
- Use 3.14 for pi

Learning Target:
- I can draw the each "face" /"shape"for a rectangular prism, triangular prism, and cylinder and then find the area of each face.
- I can calculate the surface area of a rectangular prism by adding areas of all faces
- I can calculate the surface area of a triangular prism by adding areas of all faces
- I can calculate the surface area of a cylinder by adding areas of all faces
In Class "Hands on" Surface Area Activity"
Students were given: "real life" cylinders, rectangular prisms, and triangular prisms
(blocks, cans of food, etc.,) and asked to determine the surface area of ea
Activity:
1) Trace the "faces" of each type 3-D object (cylinder, rectangular prism, triangular prism) onto construction paper. ** only need one of each type**
2) Clearly label each face with : top, bottom etc... and 3-D shape type
3) Measure and label each "face" (length, witdth, height)
4) Calculate the area of each face (use cm-- do not round until the end)-- SHOW FORMULAS and how they were used!
3) Use the area of each face to determine the SURFACE AREA of each 3-D object
SHOW HOW YOU DETERMINED THE SURFACE AREA of each of the 3-D objects
Homework:
REDO your incorrect problems 1-7 from 10.5 Practice B
*** you DO NOT need to draw the nets... you DO need to show the area of each FACE and how that is used to calculate surface area***
ANSWERS:
1) 488 square in
2) 2590 square meters
3) 1848 square centimeters
**** your answers for #4 through #7 might be slightly different due to rounding*****
4) 1250 square feet
5) 1583 square yards
6) 5806 square milimeters
7) 336 square inches

Continued practice w/ surface area and 3-D figures
Practice Strategies for solving Cylinder Problems (remember circumference of the circle = length of the rectangle)
Practiced Strategies for solving Triangular prisms:
-equilateral triangle=> 3 rectangle sides hade same area
-isosceles triangle==> 2 rectangle sides have same area
-scalene triangle===> none of the rectangle sides have same area.
Homework:
page 566 # 15-17
page 812 # 19
Answers are:
15) 108 in squared
16) 88 in squared
17) 452 in squared
19) 312 in squared
