Math Man

Sometimes these kids are too smart for their own good.

Seth and I were working on his math lesson today. With Saxon they have a group time and then they get to do the work on their own and see if they understand it. And everyday there is a number pattern and a word problem to work out in group time. This is how our group time went today.

Me- "Okay Seth here is your word problem, Jane's dog chewed the edges of her bedroom rug. The rug is five feet long and three feet wide. Jane decided to sew tape along the edges. How much tape will she need to buy? Draw a picture."

Seth- Okay so (he grabs the dry erase marker and begins drawing) lets see she has a rug.... five feet is way too big to draw up here.

Me- yeah, you can just draw a sketch.

Seth- Okay. ( drawing sketch, labeling sides) hmm, lets see take out this corner, this is going to be hard.

Me- What? What is hard you drew the picture and labeled it, what do you do next?

Seth- Well, the dog chewed off the corner, how much did he chew off? I don't know how long the side is now.

Me- Oh, yeah well the dog didn't really chew off the whole corner just nibbled it a little. Okay?

Seth- Okay, So she wants to tape the corner the dog chewed. But I still don't know how big the corner is that she wants to tape.

Me- (Oh my!) Okay look she is going to go ahead and just tape around the whole rug so that it all looks the same.

Seth- Oh that's easy, 16ft, I just add 10 plus 6.

Me- Yes.

Is this a man thing? Or possibly it's because he is a lefty and he is right brained?

Wait a minute! The rug was originally 5 ft x 3 ft until Jas er the dog chewed the edge. Now it is something less than the original dimension, so the problem becomes less precise. Maybe the lost corner accounted for at least 5 % of the total edge length, but that would mean that there would have to be at least 5 % less linear dimension. It is also possible that some of the rug had to be cut back in order to make it into a regular parallelogram with 90 degree corners. You need to take that into account; now tell me who was more preceptive...

So what you are saying is that it's a man thing.

Thanks for clearing that up dad!

I'm with Seth and Bill both, I mean come on, who is thinking of these questions? The material is seriously flawed. If you are going to have an animal damage something you at least need to say how significantly it was damaged. For instance, saying that she measured the perimeter of the rug and noticed that it was 1 foot shorter than it use to be, that would be a more understandable approach.

If they just want to know the perimeter of the rug, why bring the dog into it? Why not say that she doesn't like the color and so she is going to add a border, that would make more sense.

Not very logical for a math book.

Fortunately for you, your son already has the logical and sensible skills that every man possesses.

Oh my-never a dull moment-huh, Honey! Too bad they can't be that precise when it comes to taking out the trash. Has the bin reached it's capacity or is it better if part of it falls over on the floor because the bin is over capacity. Or can I shove this one small thing in and the lid will still close, so the bin is not really full-you get my drift?
