Jem's Nets Of Three-Dimensional Objects

Nets Of Three-Dimensional Scribe

Hi (: for friday the 19th of February, we continued doing some practice work on nets. Our job was to finish the rest of the questions of the math textbook for 5.2 chapter. If you didnt get to finish you can check out the questions on the textbook online. Now for my scribe ill be doing 3 questions they are #3, #10, and #6

Today, we worked on our foldables. We had to put it in 5.1 Views of Three-Dimensional objects.

We also had answer Communicate the Ideas in our foldables.

1. Raina insists that you need to tell her all six views so she can draw your objects. Is she correct? Explain why or why not.

-- No, because if you have the top, bottom, and sides, she wouldn't even draw 6 views.

2. Are these views correct? Justify your answer.

-- No.

Front

Side

5. Draw each 3-D object using the
views below.

9. Sketch the front, top, and right side
views for these solids.

RAQUEL'S SCRIBEPOST FOR SURFACE AREA

Yesterday, during math class we did lots of things on learning about surface area. We were reading about surface area. After, we did the reading we talked about the squares. We drew the squares on a Isometric dot paper. We learned how to draw a cube on the Isometric paper. It looked like this..

After, that we had to guess what cubes have. We learned that they have.
- 3 faces showing
- 6 faces in total
- all squares
After that, we learned about Rectangular Prisms. We drew it also and it looks like..

What we learned is that they have.
-6 sides

After, we did all that we did a foldable. What we did on the foldable is we did this..

After, we did our foldable Mr.Harbeck assigned us our homework which was :
Define:
-face
-vertex
-net
-edge
-rectangular prism

-Draw 3 different rectangular prisms and show the similarities and differences between them

-Complete your Homework book Pg. 48

and
-Find 3 rectangular prisms in your house and..
-Label them
-Draw the top, front and side view of the object
-Make sure each object is different

I'll just show you the Definitions and the 3 different rectangular prisms.
Definitions:
face- flat or curved surface
vertex- point where two faces meet
edge- line segment where two faces meet
net- a two dimensional shape that, when folded encloses a 3-D shape
rectangular prism- a prism bases are congruent rectangular
3 different rectangular prism:

The similarities are..
-They all have 6 sides
-Their all a rectangular prism
-They all have bases that are congruent rectangular

The differences are..
-The dimensions are different
-Different face sizes
-( I don't have a third one, sorry. ) :S
(by the way, dimensions are length, height, and width. )

AND....... THE END

( P.s, the font is just really messed up, I don't know why. )
REMEMBER TO COMMENT AND TELL ME IF I MADE ANY MISTAKES, THAAAAAAANKS. (:

Richard surface area foldables

Today in our math class this what we did for our foldables.

A minimum of three views are needed to describe a 3-D objects.

Using the top, front, and side views you can build or draw you 3 d object.

You also need to put that on your foldables.

kaitlin.L's percent post for Feb. 9

I am doing my percents post on a couple of the questions from my Percents test...

19. Greg's backyard measures 30m by 30m. He wants to build a small tennis court that measures 20m by 15m. what percent of Greg's backyard will be used for the tennis court?

my answer:

30m x 30m = 900m

15m x 20m = 300m

The percent of Greg's backyard is 33.34% for his tennic court.

16. Is it possible to have two fractions with different denominators and numerators representing the same decimal? explain your answer using examples.

my answer:

Yes you can have two fractions with different denominators and numerators representing the same decimal.
Example: 4/8 or 5/10 they are both 50% or 0.50

that was my percent post...... COMMENT! :)

Kisha's percent scribe

This looks confusing, but its simple. Divide 35 by 10. Divide 100 by 10. Then multiply 3.50 by 2, and multiply 10 by 2. Then subtract 35 by 7.50, which equals $28.00. Then subtract 100 by 20, and that equals 80%
