New Blog: 19 & Still Alive

Posted on by Denise Gaskins

Niner (pronounced Neener), who takes the photos for my blog header — which reminds me, we’re about due for a new one of those… — has started a new blog. She calls it 19 & Still Alive, because “the world doesn’t end when you’re 16 if you don’t go to Prom or don’t get your driver’s license. (I never went to Prom, and I didn’t go through Driver’s ED until 17, but I’m alive, amazingly.)”

There won’t be any math there, or at least I don’t expect to see any; the blog will be mostly her rambling thoughts about whatever catches her interest. But she does have a wonderful graphite drawing based on the photo Masarwa man. On her blog, you can click the image to see him up close and personal. Wow!

My New Project: Blogging 2 Learn

Posted on by Denise Gaskins

Beginning in January, I will teach a 4th-12th grade Blogging 2 Learn class through our local homeschool co-op. For now, here is my research blog, testing ideas and trying to imagine myself as a new blogger:

Have you used blogs with your students? If so, I would love to hear your suggestions and comments. And whether you are an experienced or a wanna-be blogger, please share: What do you think a “Blogging to Learn” class should cover?

Do Your Students Understand Division?

[I couldn’t find a good picture illustrating “division.” Niner came to my rescue and took this photo of her breakfast.]

I found an interesting question at Mathematics Education Research Blog. In the spirit of Liping Ma’s Knowing and Teaching Elementary Mathematics, Finnish researchers gave this problem to high school students and pre-service teachers:

We know that:
498 \div 6 = 83
How could you use this relationship (without using long-division) to discover the answer to:
491\div6=?
[No calculators allowed!]

The Finnish researchers concluded that “division seems not to be fully understood.” No surprise there!

Check out the pdf report for detailed analysis.

Math Teachers at Play #9 – Game Time! now posted. Enjoy!

Who Broke the Internet?

My Internet connection has been like a yo-yo: up and down, but mostly down. DH — who has little patience for blogging — says that’s just as well, because my main job this summer needs to be a major decluttering and housecleaning project. So I’ll be back when I can, but I don’t know how soon…

In the meantime, check out the Carnival of Mathematics #53. And be sure to send in your entry for this week’s Math Teachers at Play blog carnival, to be published this Friday at Homeschool Bytes.

Math Facts: 5 Minutes a Day

Y of x reminded me about one of my old favorite websites for math fact practice with a purpose:

5-10 minutes of daily practice will cement the math facts in your student’s mind, while at the same time doing a good deed. For each correct answer, a Free Rice sponsor donates a very small amount of rice to feed hungry people worldwide through the UN World Food Program.

Even very small amounts of rice add up. Since Free Rice started in 2007, its sponsors have bought more than 63 billion grains of rice, just by paying for one right answer click at a time.

You and your students can practice other topics as well:

Tom DeRosa of I Want to Teach Forever told me that he would love to have homeschool teachers or unschoolers contribute to his 52 Weeks, 52 Teachers Project. Just write a short response to the question:

  • “What is the most important advice you can give to other teachers?”
