Q4, W3: April 13-17 Geometry

TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #April 13-17
Unit of InstructionUnit 7: Three-Dimensional Measurements
Standard(s) Taught

MAFS.912.G-GMD.1.3: MODELING STANDARD Use volume formulas for cylinders, pyramids, cones, and spheres to solve problems.

MAFS.912.G-MG.1.1:   MODELING STANDARD  Use geometric shapes, their measures, and their properties to describe objects.(e.g., modeling a tree trunk or a human torso as a cylinder).

Learning Targets and Learning Criteria
  • calculate the volume of a cylinder, pyramid, cone, and sphere and use the volume formulas to solve problems.
  • find the volume when one or more dimensions are changed.
  • describe real world objects using geometric figures.
  • use measures of geometric shapes to find volume, surface area and lateral area of real-world objects.
  • apply the properties of geometric figures to solve real-world problems.
  • decompose a figure in smaller parts to describe the properties of the object.
Classroom Activities


  • Today you will watch five short videos on the solutions to the five problems on the Volume of Composite Figures page that you did last week.  If you did not do that yet, then please do that first.  There is a video for each problem.  In the video, I show the correct answers first.  If your answer is correct, then you can skip that video.  If your answer is incorrect, then watch the video to learn how to correctly solve the problem and correct it on your paper.  Here are the links to the videos:  (60 minutes)

  • Please watch the following recorded video which will give you some helpful information on how to solve the problems you will be working on today:  (30 minutes)

    • After watching the video, please do IXL T.12  (90 minutes)


  • Please do the worksheet “Surface Area and Volume of a Castle” (this will be an attachment in gradebook on the assignment called SA and V of a Castle).  I gave some hints about this on the video you should have watched on Tuesday.  If you skipped the video, you might want to go back and watch it!  Remember to find the volume for each of the 11 individual pieces and then add them all up.  Do the same for surface area, but remember that you do not include surfaces that are not part of the outer surface of the composite figure.  (120 minutes)
  • Please submit your answers by the end of the day on Friday in order to be considered for the prizes!  To submit, take a picture of the page with the two answers written on the space at the bottom right and share the picture with me on Remind!
Assignments Due
  • IXL T.12
