Surface Area

Some of you missed today's lesson because of band.  Here are the notes and problems from class.  There are two pages of surface area problems that I want you to work on, but you can copy down the work and answers for the problems below.  Make sure that you are using the time to help you understand and solve the problems, don't just copy answers because that won't actually help you!

There is a video at the end to help you understand further.

Surface Area!

Today we began looking at surface area!

We've used rectangular prisms for our first look, but will also talk about triangular prism and pyramids.

Tonight's homework is to find the surface area of one of your nets.  Measure in centimeters and show your work on the paper.  Be sure to label your final answer.

Geometry Word problems

Today we began working with word problems in geometry.  We completed a few volume problems in class.  Answers are below.

Tonight's homework is to complete the four word problems on your worksheet tonight.  Keep in mind that the problems could be surface area OR volume, so be careful!

Here are the first two started from class and then the worksheet if you need to print it out!

Need the worksheet?  (Yes, I know they are sideways... so is the worksheet.  If you need to print this out, copy, paste and stretch it out to fill a side of a sheet of paper.  Thanks!)

Have a great night!  Test next Wednesday, April 9th!

Practice those Volume and Surface Area problems with Fractions!

Tonight's homework is just the two Volume and Surface Area questions, but they each use fractions.  Work carefully!

The two problems:

Use the notes and videos from previous posts, your homework problems, and the yellow note sheet to help you if you get confused!

Keep reviewing, the quiz is on Friday!

Online Homework!

Good afternoon or evening everyone!  Welcome to your homework.  As you know from class, tonight's homework is to work on the online games and activities for 15 to 20 minutes.  Feel free of course to do more than that, especially if you think that the problems are fun or entertaining.  :)

Click the link or the image to go to the various sites I have found.  Try as many as you can!  (Apologies in advance if any of the links don't work or your computer doesn't like the system requirements)  Feel free to leave a comment to let me know you did your hw or share the site that you thought was the most fun!

Interactives allows you to both read descriptions of the various solids we have explored AND see the nets that can be used to create them.  Be sure to scroll down and click through the pages in the section!

More from Interactives with more of a focus on surface area and different shapes.  Again, scroll down and move through the notes.

On this page, you will see photographs of various solid shapes with links to printable nets that will allow you to make the various 3 dimensional shapes.  Print one out, fold it up (after coloring it if you want), and tape it together just like we did in class today!  (ps This is optional!)

Test your skills in finding volume and surface area!  Choose either the cube or the cuboid (rectangular prism) and determine the volume and surface area.  Be sure to grab a calculator to make it easier!

Exploding shapes.  Choose either of the links above and try to determine the volume of various rectangular prisms (cuboids) and irregular shapes by counting and rotating the shape.  Still having trouble?  "Explode" the shape and see each individual square unit that makes up the total volume!

Printable Nets.  Print out a sheet and fold it up or just explore the net for various 3D shapes.

Create your own rectangular or triangular prism by adjusting measurements, colors and sizes.  Watch the surface area and volume adapt as you modify your dimensions!

And if you are still having trouble with fraction problems, take some time to review the work from Friday's homework below:

Some more Volume and Surface Area help:

I hope that this helps and you all liked the online homework!
