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?”

Buddy-Style Math: Doing Homework Without Tears

Posted on by Denise Gaskins

My daughter Kitten strongly dislikes math when forced to do it on her own, so I am trying to get back into the habit of doing “Buddy-Style Math” with her. We take turns working the problems in her workbook: mine, hers, mine, hers, and so on down the page. We work each problem out loud, explaining how we got the answer and checking each other as we go.

In a way, it is like Charlotte Mason-style narration applied to math, since my daughter has to process her thoughts in order to explain how she worked the problem, which fixes the math concepts more deeply in her mind.

Homeschool Kids Write

Posted on by Denise Gaskins

homeschool-kids-writeNo, it’s not math, but it looks like a great way to kick-start Princess Kitten’s long-neglected blog. She sat down at the computer and browsed the links to other kids’ posts for over an hour last night, occasionally laughing out loud. Then she opened her Dashboard and started to type a response to the green assignment.

I’ll have to let her know there’s a new post up today. Check it out:

  • Homeschool Kids Write

Maybe I can even get her to send something in to the next Homeschool Kids Blog Carnival. It’s worth a try…

Update

Unfortunately, Homeschool Kids Write has disappeared from the web. The Wayback Machine link gives a taste of what the site was like, but It’s just not the same without the Mr. Linky connections to all the children’s writings.

Kitten did three of the writing assignments. And not only did she enter the Homeschool Kids Blog Carnival, she even hosted one edition!

My baby is growing up…
