A couple weeks ago, my blog was promoted by a couple of sites and the hits started flowing in. I commented to someone (most likely Gears) how it’s nice to be recognized for my blogging about engineering but frustrating for the lack of recognition for my actual engineering work. Guess I should’ve waited a couple weeks.
Normal work has also been crazy. I’ve been given full control of the Minion and have thrown him in on a new project where he’s learning everything from scratch. It’s similar to projects that I’ve done, but even more complicated and using a different program. So our next couple weeks are going to be real fun as we’re going to be trying to make our way through using this new program and occasionally resorting to the old program for reality checks.
The other serious challenge I’ve been dealing with this week is long division. It’s pretty scary stuff, especially when you have a seven-year-old who is fighting some rather strong perfectionistic tendencies. He’s been getting to the long division portions in his computer math, and he starts to shut down. I’ve been getting more and more frustrated with it, so I decided to put an end to it tonight. I went back and printed out some of the older homeworks so that we could take a couple steps back. I think the problem is that he really thinks he can do everything in his head. I have to admit that his ability to do mental math far outweighs mine: I simply have to write everything down. However, he’s starting to hit the limit of this particular ability, and so he freaks out whenever he has to do a problem where he can’t do it all in his head.
I told him that tonight’s homework was going to be doing some work sheets. With the problems written out on paper, he didn’t seem to have this idea that he had to do everything in his head. The first couple were challenges, but then he started getting the hang of things and was able to execute the last few problems very quickly. By the time we had finished, he was doing 3-digit numbers divided by 2-digit numbers with no problem. We’re going to do some more difficult problems tomorrow and then try heading back to the computer.
We tried a similar approach when he started to get stuck on multiplication a couple months ago. I guess there are some things that really have to be written out to be understood. I just hope he starts to make regular use of his notebook from here on out.

How I can tell the younger son is my child… January 28, 2012

The younger son is learning how to manipulate negative numbers in math. However, he was getting very irritated when listening to the ‘lectures’ yesterday. The lecture would use the term ‘minus’, as in -6 is pronounced ‘minus six’. Every time it did that, the younger boy would make some exasperated grunt and say, loudly, “Negative!”
I can only think this may be because I always call them ‘negative’. The term minus, to me, implies an operation. If so, he obviously picks up on subtleties a lot better than I thought.
When you think of a scientist… January 26, 2012

On the way to school yesterday, the younger boy started telling me that Dr. Frankenstein wasn’t a real scientist. I asked him what he thought of when he heard the word scientist. He was very quiet, and I started feeling anxious that this was going to end up in a “dude in a lab coat with beaker”.
I interjected, “You think of your mom, right?”
“No,” he paused for a few moments more. ”I think of someone who is already dead.”
Oh great. So to be a scientist, you can only be recognized post-mortem, right? I wondered if it was someone crazy like Tesla.
“Already dead?”
“Yeah, she discovered radium, I think.”
I was kind of stunned. He wasn’t thinking of guys in lab coats – he was thinking of Marie Curie. Upon conversing further, it turned out that he knew quite a bit about her. There was a Magic School Bus book on science fairs at his classroom, and he had read about her in there.
I had to admit that I was hugely relieved that not only did he suffer from a common misconception about what a scientist is but that his first thought of a scientist was actually a very accomplished female scientist.
Although I’m still a tiny bit sad he didn’t think of me.

Today I’m going to be working with the elementary students again. This will be interesting as I completely switched gears from what we were doing before. The stuff we were doing before was fun, but as we move through the book, it looks like they need a lot of multiplication and division…which most second graders don’t have.
Today, we’re going to learn about other number systems. In particular, I’m going to have them pick a number using Indo-Arabic numerals and ‘translate’ into other numbering systems – Egyptian, Roman, Babylonian, Mayan, and Chinese. This will give us an opportunity to talk about different bases, positional numbers (i.e. the concept of place value), and how many systems don’t have a zero. (Although, there’s debate in some cases.)
After doing the prep, I’m SO glad that we don’t use the Babylonian system. Base 60?! No wonder my math professor got annoyed when we used degrees.

Happy Hanukkah! December 20, 2011

I think running myself ragged finally caught up with me the past couple days. I was starting to get a cold a couple days ago and woke up this morning in bad shape. Fortunately, it’s not an infection…just my immune system overreacting to everything and telling me that today was a day off, whether or not I wanted it. I guess this is the up side to having the teenager home during the day now: his younger brother has this week off from school, so they kept each other entertained while I lay there in a cold- and cold medicine-induced stupor.
I thought this only happened as a student, but I guess not. Teaching is just as tiring as learning.
Despite feeling cruddy, we managed to celebrate the first night of Hanukkah. A couple weeks ago, the younger boy came to us and said he wanted to celebrate. I wasn’t sure what to do, but a friend sent me some information and I spent a bit of time researching how to properly observe it.
I have to admit that I feel a little funny observing a holiday from a religion with which I have extremely limited familiarity. I’m not sure why this is. I would never feel funny if my non-Christian friends participated in Christmas (and I have a lot that do). I’ve also been invited to participate in a Hillel meeting once. (I had no idea what was going on, unfortunately…but I was still welcome!) So I don’t think anyone would get annoyed…but it’s still an odd feeling.
We lit the first candle of the Menorah in our front window. I don’t know if any of the neighbors saw it, but if they did, I suspect they’re going to think this explains why we never hang up Christmas lights. Actually, we did hang them up one year, but we didn’t take them down until August. So now we just never bother with hanging them up.
Overall, it was fun. My friend sent us a card game that’s about Hanukkah, so we played that after lighting the Menorah. I guess I thought we had to wait until indulging in fried foods, but I guess not. Donuts, anyone?
Lexile ranges December 19, 2011

The younger boy’s school sent home a bunch of information on lexile range. I’d never heard of this before, but it’s a way to rate books so that kids are reading at an appropriate level. On the surface, it seems like a good idea: it’s very hard, as a parent, to provide reading material for your kids that’s appropriate. Aside from the basic issues of whether they’ll understand the language and sentence structures of a book, there are the themes and situations: are they too complex or adult-oriented for a child to read?
A lot of this, of course, depends not only on cognitive ability but emotional maturity, as well. I remember how my older boy started reading Harry Potter very early. Sometime in third grade, he read the fifth book. I began to wonder about him reading the fourth and fifth books at such a young age because of the adult themes. We were fortunate, however. Reading books about such emotional and adult themes started giving him words to explain a lot of his thoughts and feelings with minimal emotional fallout.
After receiving these results, I dutifully trucked my troops down to the library (no complaints from said troops) where they had a program to help us find books in the appropriate range. However, I forgot the letter with the lexile range and so had to guess where he was at. The younger boy had already been reading Magic Tree House books, so I figured some of the Dragon Slayer Academy books might be up his alley. We got those and some Bionicle books and headed home. He really seemed to like the Dragon Slayer Academy books and has been reading bits at a time. Language-wise, they seemed perfect, although their length is a bit intimidating for him.
It turned out, I had remembered the incorrect values. The books we picked were near the top of his range. And yet, I was confused. If these were supposed to be too difficult, why was he having no difficulty reading them?
Mike, unbeknownst to me, had also started looking at lexile information on specific books. He was curious where he would’ve been placed when he was in various stages of school. After we returned from the library, he started telling me about this and that he didn’t buy the results. He’d been comparing some of his favorite sci-fi books, and he was puzzled at the results. I threw out some books I read as a kid and made some comparisons. Books that I thought were very difficult showed up as supposedly easier to read than ones I’d zipped through.
We looked up the criteria for determining lexile range:
A Lexile measure does not address the content or quality of the book. Lexile measures are based on two well-established predictors of how difficult a text is to comprehend: word frequency and sentence length. Many other factors affect the relationship between a reader and a book, including its content, the age and interests of the reader, and the design of the actual book. The Lexile measure is a good starting point in your book-selection process, but you should always consider these other factors when making a decision about which book to choose.
Both Mike and I read this and shook our heads. We both had different takes on it. I found that one thing that made a book challenging for me was dealing with vocabulary. It’s not clear to me whether or not this is reflected in the “word frequency” measure. (Do they mean word frequency in the book or relative to the English language?) Mike felt he struggled most with books that had very adult themes, something not reflected in the range.
Our take on this is that this is only a very rough guideline, and probably not a good one to use. We both felt that interest in a book or topic was probably going to be a far better predictor of readability than using the lexile range. I suppose that’s what they’re saying about considering other factors.
My concern in this is that some schools go a bit overboard with these things. When the older boy was in fifth grade, he was going to public school part time. I got a couple calls from the school librarian because he wanted to check out books that were designated for 7th-9th graders. I felt this was silly because he’d been reading at above that level already, and probably had come across themes in his reading that were more adult than what was in those books. I told her it alright for him to check the books out, but she seemed to be very opposed to it. I finally gave up and told older son that he should just probably check most of his books out from the public library.
I’m hoping I don’t see something similar happen with the younger son, i.e., that he not be allowed to check books out from the library if they’re outside of his lexile range. On the other hand, I’m glad that they seem to be promoting reading at the upper end of the scale so that kids will stretch their mental muscles a bit as well as that they make the point that within any grade level, you’ll have a wide variety of reading levels. In other words, it seems like they’re trying to get rid of the fantasy that kids all read at the same level and thus require the same reading level. Therefore, while I may disagree with assessments of individual books, I think they’re definitely taking a huge step in the right direction.

A Note to Parents: Healthy Food February 15, 2012

I have a major irritation that flaired up today: parents who feed junk food to their kids…or, more importantly, my kids.
Yes, I do realize it’s Valentine’s Day and that such an occasion requires force feeding large amounts of sugar-laden artificially produced stuff to small people, as was the custom when I was in school. However, some of the parents went overboard at younger boy’s school and provided a chocolate fountain. I also realize they brought healthy stuff to dip in it (like strawberries and bananas)…but I don’t understand why they didn’t just bring the strawberries and bananas while leaving out the chocolate fountain.
Before you accuse me of being heartless (ha!) Scrooge, I am not some health nut who only feeds her kids macrobiotic foods (although I do see the wisdom in that). My problem with this is that my kids are hypoglycemic, and I’ve suffered for years with parents bringing cookies and crap like that for snacks at school.
For the older boy, his hypoglycemia results in very angry outbursts. Some of these outbursts got him sent to the principal. The younger boy, however, will be bouncing off the walls and unable to focus. If we hadn’t determined the food connection, I’d swear up and down that he’s got some sort of ADHD that comes and goes.
On the other hand, I don’t think it’s just my kid. I’ve had teachers discuss with me how a LOT of kids seem to get unfocused after having particularly high levels of sugar.
That being said, if you are a parent, please think about these things when bringing snacks. Good foods would include things like crackers and bread, cheese sticks, nuts (if no one has nut allergies), whole fruit, beef jerky, celery and carrot sticks.
Things to avoid: yogurt pops (they are LOADED with sugar); most granola bars – also loaded with sugar, although the Kashi brands aren’t too bad; fruit juice…you may as well being giving them kool aid; cookies and cake are just plain out.
We’ve made an agreement with the younger boy’s teacher that he has cheese and crackers in his backpack. If the snack tastes sweet, he’s supposed to have his cheese and crackers along with the snack to prevent a huge blood-sugar spike and crash. Prior to this agreement, my son would be coming home from school half the time, unable to concentrate on any thing aside from a video game.
I realize most people’s kids aren’t as sensitive, but it makes sense to me that you’d want to avoid unnecessary sugar anyway. However, that doesn’t seem to be the case, and it’s amazingly frustrating to deal with on nearly a daily basis. So please – before you buy the frosting-covered cookies from the bakery, see if there isn’t something even marginally less sugary. My kids and I thank you.
