T2
Use nets to find the surface area of rectangular prisms
G.4
Lesson 1
Vocabulary
Notes
Surface Area (S.A.) is the total area of all outside faces of a 3D object, measured in square units (ft², in², cm², yd², etc.)
It represents the total space covering an object's exterior, such as the amount of wrapping paper needed to cover a box.
It is calculated by adding the areas of all individual faces.

Notes
Play the first minute or so... to tease out some vocabulary
1. What is the surface area of a prism with a height of 13 cm, a length of 7 cm, and width of 7 cm? (square base)
2. What is the surface area of a prism with a height of 13 cm, a length of 6 in, and width of 9 in? (rectangular base)
3. What is the surface area of a cube with a side length of 7 yards?
Summarize
Notes
To find the Surface Area (SA) of a prism:
#1. Sketch the net
#2. Write the dimensions for ALL of the sides
#3. Use the dimensions to find the area of each of the faces
#4 Add the areas to find the total surface area
My Responsibilities
Due 3/9
1. Check-your-understanding questions (CYUQs): Do your own, you choose where to start, check your work with the students around you. If you need help, get help. If someone needs help, give help.
p767 1, 2, 3, 4, 5 (Volume 2, Chapter 10, Lesson 3)
2. Write down at least three things to remember about this topic in your math notebook (include examples)
3. Don't give up! If you get stuck, choose to persevere: review your thinking, try another approach, ask for help, search
Lesson 2
After completing the Check-your-understanding questions, which were important for everyone to do?
Pick one or two problems that you did and show your work to you seat partner.
