Exploding Bananas and Math

Share this post via email

Today I was reminded of Gorillas, a game where you lob exploding bananas at your opponent. (You can play a Flash version of the game here)

You are given two variables to control: Angle and Velocity. Get the right combination of the two, and, blam! your opponent is a cloud of red pixels.

Think about that: At the tender age of nine I was working with angles and velocity--not to mention that pesky notion of multiple possible solutions based on two variables in a function. I would not return to these concepts until I was in high school physics. And, surprisingly, by the time I got there, the subject was at lot more difficult.

Why?

Because rather than learning how velocity and angle relate to each other in a parabolic arch--ignoring, as we always do, wind resistance--I was forced to memorize the mathematical equations and computations needed to solve for the function. It was dull and uninspiring. In fact, I really didn't like it. Except for the one assignment where we rolled a marble down a ramp and attempted to hit the center of a target on the floor. That was applied mathematics. And it was fantastic.

The thing about Gorillas is that it is not--at heart--an educational game. The "educational" bits are left off (e.g. equations). So, sure, Gorillas didn't teach me the formula, but it did teach me very high level concepts. And while Physics taught me the formulas and computation, it didn't really teach me the problem solving skills.

I found the TED talk linked from Mary Mimouna's post to be fascinating. In it, Conrad Wolfram argues that we should stop teaching computation and start teaching math.

On the one hand, memorizing the basics of computation and equation building helps a ton when you're trying to figure something out. On the other hand, I think a lot more kids would discover that they love math if it had more to do with exploding bananas and less to do with "show your work" and "don't use a calculator."

The more I hear about math education, the more excited I am about MathTacular. We designed these DVDs to teach the concepts and demonstrate the calculations. I think it's a great balance.

What do you think of the Experimentation/Computation tension?

My Passport, MathTacular, and Malls

Share this post via email

The three Ms.

M1. A huge thank you to everyone who participated in the My Passport to India project. We're still waiting for all the money to come in via the mail, and we're praying that we'll meet the goal when it all arrives! Thank you, again, for your generosity.

M2. More than just MathTacular4 has been added to the MathTacular Family. We just launched the MathTacular Educational Kit for the Christmas season. This Manipulatives Kit is not going to be a permanent Sonlight item, but we are offering it now as an excellent gift for a friend or family member who may not homeschool and is looking for an excellent way to reinforce math concepts.

I just want to make sure this is absolutely clear: This Manipulatives Kit is a product Avyx created for a different market. This product is not part of the original MathTacular Tetralogy. Rather, it is an offshoot project aimed at getting the incredible educational benefit of MathTacular into homes which may not be inclined to homeschool.

M3. Malls. With the launch of the MathTacular Educational Kit, I was able to go check out one of the kiosks in a local mall. It's fun to see a product I originally created displayed in a mall.

I was even able to snag a MathTacular shirt and got a shot of the kit assembly:

That's it for this week. See you on Monday! ...hmm... the fourth M <smile>.

Count Your Many Blessings

Share this post via email

I want to be known as a thankful person. I love that old song "Count Your Many Blessings" because it reminds me that life doesn't have to be perfect in order for me to feel blessed. So I'd like to share here a quick, incomplete list of things I'm thankful for:

  • Chocolate: It needs no further explanation.
  • Family: I really like my kids. I like to be with them and I like how they think. I'm proud of the people they've become.
  • Grandchildren: It's amazing how bright they are! Their antics and sayings lighten my heart and make me laugh.
  • Marriage: For John and me, the benefits greatly outweigh the challenges.
  • My modest home: I'm thankful it's not bigger when I go to clean it!
  • Books: I think I'd rather read than eat ... and I do love to eat.
  • My church: This past year we gradually transferred from the founding senior pastor to a 27-year-old senior pastor. I've never seen such a thoughtful and gentle transfer—amazing.
  • Telephones: What a blessing to be able to keep in touch with Amy and Justin who live out of state.
  • Gardening: There's something about getting my hands in the dirt that builds up my soul.
  • Homeschoolers: Moms who invest in their children to raise up the next generation—my hat is off to you!
  • Good coffee: I almost always carry a mug full of coffee. My friends and family say they can always find me by following my trail of misplaced mugs.
  • Health: Many family members and fellow Sonlighters world-wide deal with complex health issues. I am grateful for health.
  • Garage sales: What can I say? I love heading out to the sales on Friday mornings with my daughter and daughter-in-law. It's such a privilege to spend this fun time with them each week.
  • Friends: I love the simple pleasure of laughing and being together.
  • My job: I love what I do!
  • Quiet time: The Lord wakes me up each morning (without an alarm clock) to spend time with him. This is a truly precious time.
  • The Mission India project: Since one of my passions is to raise up children with a heart for the world. I'm grateful for the chance to learn about a needy part of God's world, to be able to pray, and to link arms with other Sonlighters and make a huge difference financially! (If you don't know what I'm talking about, click here.)

As I think of these blessings, I'm drawn toward Psalm 103, a Psalm of David:

"Praise the LORD, my soul,
and forget not all his benefits—
who forgives all your sins
and heals all your diseases,
who redeems your life from the pit
and crowns you with love and compassion,
who satisfies your desires with good things
so that your youth is renewed like the eagle's.
... The LORD is compassionate and gracious,
slow to anger, abounding in love."
(Click here to read the whole Psalm)

God truly is good and gives us far more than we deserve. If you haven't yet, may my inadequate list galvanize you to reflect about what you're thankful for. I'd love to hear from you.

And I do pray you have a blessed Thanksgiving holiday.

Blessings,
Sarita

...my computer just don't know who you are.

I got a letter yesterday from my insurance guy. It was one of those "you mean so much to us, we made you a few dozen address stickers with a fun little graphic on them" kind of thing. The trouble was: The stickers had someone else's address on them.

Nice.

I was so inspired by their obvious care and attention to detail, I gave them a call.

"Hi, Luke," said the cheerful guy on the other end of the line.

'Weird,' I thought to myself, 'he certainly seems to know who I am.'

After a few moments, the insurance guy had found the problem. Their office had my information correct. But the marketing database had it wrong. That would explain how they were able to bill me and yet not know my address.

The world was beginning to make sense again.

And, working at Sonlight, I can relate. It would be nice to have a central system that handles everything we do... but such a piece of technology--if it exists--is beyond my reach. And so, I realzied, it's entirely possible that something fishy may happen to you as you interact with Sonlight over the years.

It's not because we don't care about you. But our computers may have no idea who you are. Just remember, like I did with my insurance company, please contact us if you have any questions or concerns. We'd love to help!

Speaking of marketing... don't forget to check out the Christmas Sale.

And if you haven't given to the Mission India project yet, you need to do it before the end of today to have your gift matched.

What's the oddest piece of mail you've received?

Back to the Drawing Board

Share this post via email

You arrive on a page--like this blog--and you decide you don't want to be there--which would be very unlike this blog <smile>. So, you click the little "back" arrow in the upper left of your browser and return to where you had been.

Easy. Well-known. Common.

But how do you visually tell people to back up? Specifically, how do you graphically communicate with just a couple of scribbles that this button will take them back a few steps?

I started with the image in the upper left (below) because it looks a lot like the "expand" button on video players. My thinking was that by stepping back you are expanding what you can see. ...trouble is, people assume that the button means "make full screen" instead of "back up." Right. That makes sense.


Images for Going Back

So I added an arrow pointing back at you (bottom right).

"Why is it pointing at me? What do I have to do with that button?" my coworker Barb asked me when I showed it to her.

<sigh>

So, it's back to the drawing board for me.


Back Icon?

How would you communicate with an icon in the picture above that clicking it will take you ten steps backward into the parking lot?

P.S. Next week, friends. Next week I hope to share this project with you. Unfortunately, being stuck on the "back button" is slowing me down.

Balancing Act: Social Media and SEO

Share this post via email

There's a tension in the web world. It's a war between man and machines. We built them, they have gained a perceived level of sentience, and now we must beat them back. I can't wait for the blockbuster film next year:


Social Media vs. SEO

See, I need Sonlight's web pages to be helpful. To be helpful, they must contain information that is easy to read and talks to you about the subject you're interested in. "Sonlight's Core programs form the foundation of your school year. Easily add Language Arts, Science, Math and Electives to the Core's History and Literature." That's the kind of thing I'd want to include on a page or blog post about Sonlight's Core programs.

But I'm not creating web pages just for humans. In order for humans to find these pages, a roving bot must first decide the page is important enough to show to a human. So I have to change the text to make it clear to a computer what I'm talking about: "Sonlight's Christian homeschool curriculum Core programs form the foundation of your homeschool year. Easily add Language Arts, Science, Math and Electives packages to your Core History and Literature homeschool curriculum programs."

Wait, there's more.

I also need to make it extra clear in the code that I'm super serious about this. So I add all this hidden text and emphasize things in code to ensure the search engine bot puts my page where you can find it:

Christian Homeschool Curriculum Packages

I've been trying to balance the two as I've been updating some homeschool curriculum package pages on Sonligth's homeschool curriculum site. I want you to be able to Buy Homeschool Curriculum for Your Homeschool when you search for Christian Homeschool Curriculum online. And yet... I want it to be readable.

Have you had to balance man and machine? Who won?

P.S. Have you considered Sonlight's Christian Homeschool Curriculum Packages for your homeschool curriculum needs?

P.P.S. Make it stop!!!

Multiple Choice: Why Is Homeschooling Great?

Share this post via email










Submit

Please use a #2 pencil and fill in your choice with a complete, dark circle.

  1. Customizable learning environment
  2. Parent-child interaction
  3. Low teacher to student ratio
  4. Nurturing environment
  5. a through d
  6. No Scantron®

I got thinking about this when I saw the comic in this post.

I'm not a fan of the standardized test. There are much better ways to go about measuring understanding, retention, application, recall... You know, all those terms we imply when we talk about "learning" and "education." Unfortunately, since schools don't have option e above, they must resort to the tools of f.

But here's what struck me today as the image of multiple-choice teen gnawed at the back of my mind: My friends have always thought just as creatively as I do. In fact, many of them are more brilliant than I'll ever be.

So, sure: Smile sadly at the incredible limitations mass produced education demands. Be thankful for the privilege we have to educate our children at home. Consider the many blessings we enjoy as homeschoolers. But do not, do not, stick your nose in the air and believe for a minute that the children in "the other system" can't function as well as yours.

I am well aware that the school system is flawed. In spite of this, my friends have turned out amazingly well.

The encouragement we should take from this, in my mind, is we don't need to worry about our own children. We're giving them so many fantastic opportunities, what gaps and struggles we encounter can and will be overcome with a life-long love of learning.

What have you found makes your homeschool experience great?
