Surface Area

Surface Area is the area of the outside of a shape. Im going to show you how to get the surface area of a rectangular prism.

First you need to make a net. The net shows the front, the back, the top, the bottom, and the sides. But the front and the back are the same area, the top and bottom are the same, and so are the sides.

Once you have your net. You use the simple formula for adding the measuerments. (LxW)(WxH)(HxL) Since the net is flat, you have to square the number.

Well after you use the formulas with the measurements, you can add it up and get the surface area. You can use the example I gave you to help better understand.

Volume:
Volume is how much the entire shape takes up. To get the volume of a rectangular prism, you multiply the length (L), width (W), and height (H). That will get you the volume of the entire shape. The answer, is always cubed or in 3. ex. 18 cubic(3) centimeters.

- What was the hardest thing about this unit?

I did not find this unit to be hard at all, but I found some of the work we did to be very annoying.
It was mostly the fractions that were harder to convert, or some of the sub questions that required more thinking about. Not that I don't like thinking and doing math, but I think that everyone would agree that the sub questions where we had more than one extra person to divide the subs by to be annoying. Like instead of 8 people and 7 subs, having 7 subs and 10 people. Grrr...

- What do you understand now that you did not understand before?

I think that I found some new ways to solve problems. I used to solve everything the same way, and I found that my way of solving problems was not always the most efficient thing.

- If you had to teach your parents about fractions, what would it be and how would you do it?

I would show my parents how to use clocks, and how to convert fractions into time, such as 2/5 of an hour would be 24 minutes.
I would do this by drawing them purdy pictures in which their old eyes could easily understand. ^_^

What was the hardest thing about this unit?
Showing 1/5 and 1/10 on the clock because you have to get the percise location.

What do you understand now that you did not understand before?
Showing the clock method because before I just showed my work by using the rectangles.

If you had to teach your parents something about fractions what would it be and how would you do it?
I would teach my parents how divding and fractions are related. I would show it and prove it to them by either drawing a rectangle and dividing it or drawing a clock and dividing it.

what was the hardest thing about this unit?
The hardest thing in this unit for me was cutting the subs for each kid.

What do you understand now that you did not understand before?
Now I know how to add two fractions together, and how to use a clock to add fractions.

If you had to teach your parents something about fractions what would it be and how would you do it?
I would teach them how to add fractions together. I would teach them how to use the clock method that we learned in math. I would have to say that 1/2 of the clock is 30 minutes because it is cut in half. Then 1/3 of the clock would be 20 minutes. So if you add 20 + 30 it would equal 50.Now the fraction would be 50/60 or in other words it would be 5/6.

1/2 + 1/3 = 5/6
30 + 20 = 50/60

Chantal's B.O.B

What was the hardest thing about this unit?
The hardest thing about this unit was dividing the subs.
What do you understand now that you did not understand before?That you use clocks to divide all the time.If you had to teach your parents something about fractions what would it be and how would you do it? About using the subs and how it was hard at some times to divide them so that they would be equal.

Jessica's Blogging on Blogging

What was the hardest thing about this unit?
- The hardest thing for me about this unit was doing the Krypto.
Some of the questions were easy but when people were giving answers and using brackets , it made me confused. Another thing that made this unit hard in the beginning was using the clocks to explain fractions.

What did you understand that you didn't understand before?
- In the beginning of the unit I didn't really understand how to find out if a fraction is bigger than another one using a clock. But by the end of the unit, I started reading other people's blog's and it starting making more sense being explain by other kids.

If I had to teach my parents something about fractions, I would teach them how to use a clock to explain it & i would also teach them how to use a common denominator to do it.

What was the hardest thing about this unit?

• The hardest thing I learned about this unit was getting how much each person got with the subs, but I had managed to understand it.

What do you understand now that you did not understand before?

• I didn't understand how to get the time with the clocks.

If you had to teach your parents something about fractions what would it be and how would you do it?

• I would want to teach my parents to use clocks to help them in fractions and I would give them easy questions such as 1/2 + 1/2 = 60 min.

Mary's bob

What was the hardest thing about this unit ?
I'd have to say that the hardest thing about this unit, was adding fractions together. I seriously didn't know how to do anything like that, but when i learned about the clock method, it made it soo much easier.

What do you understand now, that you didn't understand before ?
I didn't understand how to add fractions before. Well, i knew how to do it in grade 6 and 7, but i guess i just forgot how to do it over the summer. The clock method really helped me learn to understand how to add fractions.

What would you teach your parents about fractions, and how would you teach them ?
I'd teach them how to do the clock method of adding fractions. First, i'd give them an easy questions, like 1/2 + 1/4. They should know what half an hour would be, and they always say QUARTER after whatever, when it's 15 after. So i'd just tell them, half an hour + 15 minutes, would be 45 minutes. Since it's out of 60 minutes, the denominator would be 60. 45/60 = 4/6 would be the answer.

Hardest thing in this unit?
The hardest thing in this unit was learning about fractions. The hardest thing about the fractions were making them equal.
What do i understand?
I understand how to do those kyrpto's. The kyrpto's weren't that hard for me.
What and how would you teach your parents?
If I could teach my parents something I would defintley teach them fractions. This way everything in the house would be equal :)

Hardest thing in this unit?
That hardest thing i this year was the questions at the beginning of the year "krypto" i thought it would be easy to do but it took alot of time to do it, but ever since we did that it got me thinking alot while doing math. I also thought the hardest thing, was doing that first test.

What do i understand?
I understand alot of things now, like while doing the sub questions it doesnt really matter if they have the same fraction it also depends on how big the sub is too. I always looked at it in one way. But now i know theres other ways. I also learned how to use the clock method now. I never use the clock way but now i do, since it helps alot with fractions.

What and how would you teach your parents?
I would teach my parents how to do krypto because since its like a math game kinda they wouldn't know how to do it, and if i tried teaching them the other stuff we learned they would say they already know how to do that. so i would just teach them kryto.

What was the hardest thing about this unit?
The hardest thing was first using the clock for fractions.

What do you unde rstand now that you did not understand before?
How to find out time using fractions.

If you had to teach your parents something about fractions what would it be and how would you do it?
I would teach them how to use a clock to figure out how much time a fraction is, by using the fractions as time in an hour with a clock.

What was the hardest thing about this unit?

- The hardest thing about htis unit was doing all of the sub questions. Some questions being harder than others but by the end of the whole unit it became very easy. Another thing I found harder than i expected was Crypto, depending on the numbers. It really gets you thinking and sometimes is quite challenging.



What do you understand now that you did not understand before?

- I now understand that when you are trying to compare fractions you need to have the same size whole to do it accurately. Eg. 1/2 of this o is smaller than 1/2 of this O. I also now understand there are many different ways to answer one question and that you should always show your work if you can in two or more different ways. I now know not to look at fractions in only one way, esspecially when adding or comparing. Using the Clock method really helps and makes life so much easier.

If you had to teach your parents something about fractions what would it be and how would you do it?
- If i was to teach my parents something it would have to be when comparing fractions it is much easier to use a Clock. I would explain to them that when comparing these to fractions 2/3 and 7/12 can be done wihtout finding a common denominator. You just use a clock as your example. One third of a 60 minutes is 20 minutes so you times that by 2 becuase there are two thirds. So 20+20=40 so that would be 40/60 or 4/6. Then you would look at 7/12 and the clock is divided into 12 parts each worth five minutes so you would do 5 x 7 = 35. That would be 35/60 Then you would compare 35 minutes of an hour to 40 minutes of an out and obviously 40 minutes is larger so in total 2/3 is the larger of the two.

What was the hardest thing about this unit?

I think the hardest thing about this unit was when we had to cut up the subs into equal pieces for a number of kids.

What do you understand now that you did not understand before?

I understand now how to add fractions using clocks.

If you had to teach your parents something about fractions what would it be and how would you do it?

I would teach them how to add fractions using the clock.

Many of us have learned many different things over the period of 1 month and a half.

Hardest thing in this unit?

That hardest thing i this year was in the beginning of the year when we started doing krypto , it took me longer then i expected to finsih it. At first i thought it was easy , but it ended up making me think a little harder.

What do i understand?

I understood the clock fractions and how some fractions can relate to a clock. I also understood some of the sub questions after a few times we did it.

What and how would you teach your parents?

I would teach my parents about how the size matters in fractions and how to use a clock to help solve fractions. i will show them how the size matters by using examples in the food they make. i will show how to use a clock to help solve fractions by showing them the blog site and showing them examples

What was the hardest thing about this unit?
The hardest is probably cutting subs and explaining things.

What do you understand now that you did not understand before?
I understand more about how fractions work, that the whole matters,
and how to use it.

If you had to teach your parents something about fractions what would it be and how would you do it?
My mom's smarter than my dad, but she needs to work on dividing dinner.
I'll teach my dad how to use and divide fractions.

What was the hardest thing about this unit?
Probably when we started adding fractions.

What do you understand now that you did not understand before?
Adding fractions, it was confusing before we used a clock.

If you had to teach your parents something about fractions what would it be and how would you do it?
I'd probably teach them adding fractions ( what a surprise, right?) and I'd use a clock.
