Question 1

I watched the videos for all of these but I still don't get problems 2B and 2A.

Accepted Answer

No, it's easy it's just that you have to split them apart and then find the height for the first one.

Question 2

This was not as easy as the two videos above it make it seem.

Accepted Answer

I totally agree. In the videos he does all the special colors to draw and it kinda distracts you from the actual learning of it. In the videos it looks very simple and easy, but when you are actually doing it ends up being confusing and you have many questions. At least that's how it is for me. If I was to make the videos I would try to focus from the point of view of someone who does not get the math instead of from the point of view of someone who does get it showing you it. I think that the hints are more helpful because they are made for someone who is having a little trouble with the math. The bad part is though that if you use a hint that helps you it automatically says you got it wrong, but if you watch a video that makes you more confused you get energy points for watching it.

Question 3

Is there a faster way to do the section with decomposing figures with unit cubes?

Accepted Answer

Yes there is a faster way, if the rectangular box-shaped pieces have a common dimension (that is, the same length, same width, or same height).  For example, if the pieces have the same height, you could find the area of the base of the whole figure, by adding up areas of the rectangular bases of the pieces.  Then you could multiply the area of the base of the entire figure by the height to finish the problem.

Question 4

I watched both videos and pay attention and still don't get 2A and 2B.

Accepted Answer

Basically, you have to split the shape into two rectangular prisms, then find the volume for each and solve.

Question 5

Okay, so I clicked on the next practice and made sure I had finished this one and now it's making me restart the whole thing.

Accepted Answer

it does that to everyone i think -_-

Question 6

In the videos it looks very simple and easy, but when you are actually doing it ends up being confusing and you have many questions. At least that's how it is for me.

Accepted Answer

Well, I think he’s just trying to COLOR CODE. And even if he does use an abundance of different colors, it’s easy to understand what he’s talking about. And basically if you get stuck on the colors, you’re just too focused on them. He’s just trying to make it more understandable. And even if it does distract YOU. It could be easier for younger kids to understand.

Question 7

In school do you think it is fun.

Accepted Answer

yes it is.

Question 8

Can you break the shape anyway you choose or you have to break the piece by what they want you to do?

Accepted Answer

You can break up the shape into non-overlapping pieces any way you want, as long as you correctly find the volume of each piece and correctly add up the volumes of all the pieces.  
(Note that depending on how you choose to break up the shape into pieces, you may sometimes need to perform addition and/or subtraction to find the correct dimensions of each piece.)

Have a blessed, wonderful day!
