Watch these videos as many times as you need to in order to come to class ready to work!


 * MONDAY HOMEWORK**
 * KNOW SURFACE AREA AND VOLUME OF PRISMS AND CYLINDERS**

media type="custom" key="13520120" This is a helpful video from Khan Academy on the surface area and volume of cylinders.

media type="custom" key="13520488" Mr. Blue is only clay but he seems so real! This stop-animation video is good--even if you already know how to find surface area of a cylinder, it helps make the concept stick.

media type="custom" key="13520598" This comes direct to you from Lisbon! It's called "Math Minute" but it's really four minutes. The clear and visual explanation is excellent for really understanding the concepts.


 * TUESDAY HOMEWORK**
 * KNOW SURFACE AREA AND VOLUME OF PYRAMIDS AND CONES**

[|Dr. Berger on Surface Area of Pyramids and Cones] This video aligns perfectly with the book page 10-5. Be careful to understand "slant height."

media type="custom" key="13520564" This is a straightforward explanation of how to find the volume of a pyramid. The drawing is especially clear.

media type="custom" key="13520696" The voice is a little odd in this video for finding the volume of a cone but the visuals alongside the formulas are excellent for seeing the concept clearly.


 * WEDNESDAY HOMEWORK**
 * KNOW SURFACE AREA AND VOLUME OF SPHERES**

[|Volume of a Sphere] Again, with Dr. Berger, aligned with our book, 10-6.

[|Surface Area of a Sphere] Dr. Berger demonstrating how to find the surface area of a sphere.

media type="custom" key="13520142" Another good Khan Academy video about finding the volume of spheres.

 * THURSDAY HOMEWORK**
 * 1) **HAVE SCALE DRAWINGS OF ALL OF YOUR 3D FIGURES COMPLETE WITH ACTUAL MEASUREMENTS.**
 * 2) **CALCULATE THE TOTAL VOLUME AND SURFACE AREA OF YOUR FIGURES--REFER TO THE ABOVE LESSONS OR YOUR TEXTBOOK IF NEEDED--YOU MAY USE CALCULATORS BUT YOU MUST SHOW THE FORMULAS YOU USED AND THE ACTUAL NUMBERS YOU USED.**
 * 3) **BE PREPARED TO ASSEMBLE YOUR MATH SCULPTURE! (THE TIME TO BUILD INDIVIDUAL FIGURES IS OVER.)**

[|Interactive 3D Geometry] This is an excellent website for exploring 3D geometry. Scroll down for nets on interesting 3D figures.

[|Exploring Geometric Figures] Another good one. http://www.math.com/tables/geometry/surfareas.htm Need a revision on your formulas? This is the perfect place. http://www.math.com/tables/geometry/volumes.htm Same here.
