12.4- Volume of Prisms and Cylinders

Today we started our discussion on volume of three-dimensional solids.  We began by looking at prisms and cylinders which have the same formula for finding their volume- calculating the area of the Base multiplied by the height of the solid.

Tonight's homework is P. 822-824 #3,7,11,15,19, and 21

Surface Area Review and Logic Puzzles

Today we reviewed what we have learned so far about Surface Area.  Please be sure that you have a good understanding of Surface Area so that we can move on to Volume tomorrow.

For homework, you received two logic puzzles in class.  You are to solve them for homework tonight.  If you need help, here are some websites that give some suggestions on how to solve them:

Ch. 1-11 Test and Corrections

On Friday you received your Chapter 1-11 Test.  Test corrections are due on Monday, unless you need extra help- in which case you should come see me at lunch on Monday, and you can work until Tuesday to complete corrections.  PLEASE SEE ME if you are having trouble with your corrections!

Extra Credit Assignment

Hi everyone, please remember that your extra credit drawing is due tomorrow.  The more creative and detailed, the more points you will receive toward your project average.  All missing assignments are due tomorrow as well.

Chapter 10 Review and Extra Credit Project

Today we celebrated Pi Day and the culmination of Chapter 10 by working on an extra credit project.  Your project is to create a drawing using circles, lines, and parabolas and labeling each equation of each figure that you draw.  This extra credit project is due on Friday and points will be awarded based on creativity and detail.

Also, please visit http://www.classzone.com/cz/books/geometry_2007_na/crossword.htm?id=xword_ch10 and complete the Chapter 10 Crossword puzzle.  Either email me a screenshot of your results (email to bergerj@nestmk12.net) or print out your finished puzzle.  This is due by tomorrow.

Please also study for you Cumulative Test which will be on Wednesday (Short Response) and Thursday (Multiple Choice).

11.6- Area of a Regular Polygon

Since I know we covered a lot today about the area of regular polygons, please take a look at these videos for a more complete understanding of the material:

http://www.brightstorm.com/math/geometry/area/area-of-regular-polygons

We will continue talking about this on Monday

Tonight's homework is P. 765-766 #7, 11, 15, 18, and 21

You will have your next Cumulative Test next week on Wedensday (Free Response) and Thursday (Multiple Choice).  Remember this covers everything since the beginning of the year.

Locus

Yesterday and today we talked about the six fundamental loci constructions.  We also learned how to find the locus of a combination of conditions.  See this video for help on the concept of a locus (keep in mind, we are only concerned with 2-dimensional loci at this point): http://www.brightstorm.com/math/geometry/circles/locus-and-definition-of-a-circle-and-sphere

For tomorrow, please complete your Chapter 10 Study Project.  See the previous post for the terms: http://nest8thgrademath2010.blogspot.com/2011/03/chapter-10-study-project.html
