This week we are covering Volume and Surface Area of three-dimensional shapes. We will be taking notes in our math journal and I do have copies if you are absent. I have also copied extra STAAR Math Charts that you can pick up in the classroom.
Below are some videos that can be found on Khan Academy and you can do a 3-2-1 Response for Extra Credit. I must see 3 sentences of what you learned, 2 sentences on questions you still have and 1 sentence on something that stuck with you. WITHOUT COMPLETE SENTENCES you will NOT get credit!
Volume of a Sphere
Volume of a Composite Shape
Solid Geometry Volume
Cylindrical Volume and Surface Area
This Thursday we will be having a Volume and Surface Area Quiz. I will also be checking math journals for the Volume and Surface Area notes. These two things will be the last grades for the Six Weeks. Report cards will go home next week.
Volume Of A Sphere
ReplyDelete3 things I learned
1.The formula to find it is 4 × π × r2.
2.It is symmetrical.
3. The distance from the center of a sphere to its surface is called the radius.
2 things I have question about
1.Would each side have a certain measure?
2.What would we multiply the measures from?
1 thing that stuck
1. The sphere is symmetrical all the way through.
Cylinder Volume and Surface Area
ReplyDelete3 things I learned
1.To find the volume of a cylinder you also need to find the area of the base.
2.The formula for the volume is V-Bh.
3.The formula for the surface area of a cylinder is 2 π r2 + 2 π r h.
2 things I have questions about
1. Why do we have to use two different formulas ?
2.Is the surface area the distance around ?
1 thing that stuck
1. You need to find the area of the base first.
Volume of a Composite Shape
ReplyDelete3 things I learned
1.A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).
2.If it has two basic figures it is a Composite Shape.
3.You also have to find the base of the area for this.
2 things I have questions about
1. Can we also find the perimeter for this shape.
2. Can you use the same formula with every different composite figure.
1 thing that stuck
1.The shapes have to be congruent.
Volume of a sphere.
ReplyDelete3 sentences of what i learned-
-i figured out how to find the volume of a sphere.
-I found out how to write the formula for the volume of a sphere.
-I realized you always must use the radius and not the diameter in the formula.
2 things i have questions about-
-Do you always use that formula for the sphere?
-Why do you use 4/3 in the formula?
1 thing that stuck with me-
-One thing that stuck with me, is always use the radius.
3 things i learned-
ReplyDelete-How to find the volume of a Geometric Shape.
-The formula of how to find the volume of a triangular prism.
-The formula of how to find the volume of a cube.
2 things i still have questions about-
-Why do you a 1/2 in the formula of the volume for a triangular prism?
-Is it really that easy to find the volume?
1 thing that stuck-
-Your always multiplying length times width times height.
3 things i learned-
ReplyDelete-I learned how to find surface area.
-I also learned how to find the volume of a cylinder.
-I learned the formula for surface area.
2 things i still have questions about-
-Is the formula for surface area the same for every shape?
-Why doesn't he just multiply by pie?
1 thing that stuck-
-One thing that stuck with me, is you have to find the area of the base before anything else.
