AAAspell.com Is Free Online

I really like AAAmath.com; it’s worth its weight in gold. You can use it online for free or order the CD. It goes way beyond the basic functions of + - x /.

Just recently, the person who gave us AAAmath.com has started AAAspell.com. Just type in the spelling words for the week and your student can practice them online. Of course, I think that other methods of spelling practice should be used in addition to online practice, but AAAspell.com can be another way to keep spelling practice from getting boring — you know, add a little variety to the mix.

We bought two games of Scrabble just so we could have enough letter tiles to spell words for spelling practice.

Added a New RAQ

As promised many moons ago, I am announcing another RAQ page. This one is about “horrid math woes.” Basically, it’s about some students taking too long to complete a Saxon math lesson.

A Dime Is Worth Two Pennies

A dime is worth two pennies.

Is this a statement that we’ll soon be teaching our home educated youngsters?

Well, it could be if you believe the recent news. I have posted on this subject before, but now it’s taken a dark twist. They may decide to change all our pennies into 5-cent pieces. They’re worried that people will stop spending their pennies because they are worth more than 1 cent which will cause a penny shortage.

If it weren’t for pennies, though, I couldn’t have taught my children what centum meant with such ease. How will we so easily teach that our money is based on the decimal system? And decimals are easy to learn because of the penny, too.

Think of all the sayings that will have their meanings twisted:

  • Pennies from heaven
  • A penny saved is a penny earned.
  • Penny wise, pound foolish
  • A penny for your thoughts
  • Penny pinching
  • That’ll cost a pretty penny.
  • A bad penny always turns up.
  • In for a penny, in for a pound
  • Um …

But it’s not like the U.S. is the only country with copper-ish coins. Canada has pennies and so does the U.K. In fact, the U.K. has these whopping two-pence pieces. What will they do with those? Nothing? Do they already have laws in place stating that you can’t melt down coins? Our law just changed last month as the post link to above noted.

What would pennies be called if they’re worth 5 cents? Fippence? Brown nickel? Copper half-dime?

The Fox article states:

“History shows that when coins are worth melting, they disappear,” Velde wrote.

So are you hoarding your pennies? That would be a good return on your money if you are. 1 penny = 5 cents.
I thought this part was rather interesting:

Raw material prices in general have skyrocketed in the last five years, sending copper prices to record highs of $4.16 a pound in May. Copper pennies number 154 to a pound. Prices have since come down from that peak but could still trek higher, Velde said.

So, we could do some “real math” problems with that info. All we need is today’s copper prices … wait. Pennies aren’t full copper, so that won’t work.

It seems that modern (post ‘82) pennies are mostly zinc. I guess that info above about 154/pound would only work with pre-’82 pennies.

And what about nickels? They’re still worth more than 5 cents. Would turning pennies into 5-cent pieces solve that problem? I don’t see how. Maybe their value will be changed, too.

I Thought It Must Be a Typo

I was reading Cynthia Walker’s opinion piece in the Gilroy [CA] Dispatch where it states that only 0.62 % of high school graduates are placed in college-level math classes when they enroll at their local college.

I read “… .62 percent …” and thought, “Well, that got translated wrong. That’s less than 1 percent. That can’t be correct.” And yet it is! Less than 1% of Gilroy High School students who go onto Gavilan College are able to be placed in college-level math courses.

I’m wondering, “What is going on?” It’s not like they’re all at the beach instead of fiddling with x and y because Gilroy’s not near the beach. So I searched out the original article that Cynthia Walker was referring to: Most Grads Unprepared for Gavilan. The article didn’t tell me the cause of this deficit, but I did find out that these students have English as their first language. So. Hmmm.

Anyway, Cynthia Walker is a homeschooling mom who’s currently teaching at a homeschool co-op. She likes Saxon and used it with her students at her home. She explains why she likes Saxon in this article. At Live Oak Academy, the co-op’s name, she is required to teach from Jacobs and Foerster. She prefers Saxon.

In case you’re dying to find out, I taught my son out of Foerster. It’s excellent, imo, but doesn’t have spiral review. You have to make your own spiral review by doing the evens for each lesson and picking up the odds from previous lessons. It works just fine as long as the instructor has the few extra minutes it takes to plan a lesson.

If I had it to do over again, I would still use Foerster for Algebra 1 with my son—he didn’t get along with Saxon. However, with my daughter we’re using Teaching Textbooks (TT). My son used TT Alg. 2, but it was a bit too easy after Foerster. TT is an extremely simple product to use. Each book (Pre-Algebra, Algebra 1, Geometry, etc.) comes with a set of CDs to use on the computer that teaches lesson slowly and methodically and with good graphics. All examples are shown step by step and so are the solutions. It’s like a dream come true for the homeschooling parent.

We didn’t use Jacobs for algebra, but my son used it for geometry. He used the third edition, which is nice and colorful. Harold Jacobs really loves geometry, and it shines through in the problems he gives students. They’re so creative and interesting. The book is organized nicely also, making it easy to learn/teach from.

Cynthia Walker thinks that if Gilroy United School District (GUSD) would only use Saxon math texts that all its math problems would be solved. She does provide plenty of anecdotal evidence to demonstrate that her own homeschooled students were more than prepared for college-level mathematics after using Saxon mathematics texts. However, I don’t think Gilroy’s problems will be solved so easily.

Do you know why? It’s because homeschooling outcomes are not easily replicated in the classroom setting. What happens in the homeschool can rarely happen in the classroom. Mom vs. trained teacher. Doing the work on one’s own bed vs. at a desk in a room full of people. While eating popcorn vs. starving. Not to mention that there’s a better than average chance that the objectives and methods are going to be different, too, even though the same materials are used. I maintain that homeschooling outcomes are not easily replicated in the classroom setting. It’s nearly impossible. I doubt that the math textbook the GUSD is using is really the culprit.

Which puts me right back to the question I asked at the beginning: What is going on? Why are only 0.62 percent of Gilroy graduates entering Gavilan College prepared to perform college-level mathematics?
