The Ultimate Cereal Box - Student Examples

Well we are fresh from February break and wrapping up our unit on Surface Area and Volume.  Today we made our own formula sheets from Page 222 in the textbook (these will be used for our exam) and then began to finish our cereal box designs.  Each student must hand in their calculations, net, cereal box and advertisement by Friday, March 2.  Our unit exam will be Wednesday, February 29th.  There is a Practice Test in the textbook on Page 226 and also a Review on Page 223 for extra questions.  These skills are used often in future math courses!

The Ultimate Cereal Box

"For years and years you have sat at the breakfast table staring at the same old cereal boxes - always rectangular, always boring.  Have you ever wondered why the cereal companies always put their product in rectangular prisms?  Do you know of a better polyhedron they could use?  Well, here is your chance to do some exploring!"

Each student is responsible for designing a cereal box that has maximum volume with minimum surface area.  They must defend their design from multiple perspectives and then construct it!  They will also be responsible for designing the cover of their cereal box as well as creating an advertisement to promote all that they have to offer.

New Semester!

Welcome back to a brand new semester and a few changes to the schedule.  Our geometry unit has carried over from Semester #1 and we hope to finish it by February break.  We have been working very hard on surface area and volume of rectangular prisms, triangular prisms and cylinders:

M.O. has summarized some key points very well on her blog.  She also found a volume game sure to help out with rectangular prisms!

K.G. found a website that lists the important formulas.

K.R. linked to a youtube video tutorial that helps you to find the volume of a cylinder.

We are going to be doing a project next week that involves surface area and volume so stay tuned for that!
