Homeschool Freebie of the Day (which introduced me to Number Stories of Long Ago) shares another gem today: an mp3 recording of The Arithmetic Fairy, by E. Nesbit, one of my family’s favorite authors.
Young Edwin is an English schoolboy who deplores his daily math class. He wishes he could easily solve the problems he faces each day…
You can download the entire book of fairy tales from LibriVox:
“The Arithmetic Fairy” is chapter 7. Enjoy!
Students headed into finals week need to blow off some steam, so let’s have a little fun with calculus. Hey, Niner, does this look familiar?…

I’ve put the word problems from my elementary problem solving series into printable worksheets:
I especially like the “4 layers of a story problem” concept, which helped me understand how Dan converts textbook problems into What Can You Do With This? challenges.
Featuring a wide range of topics, from an early arithmetic game to a logarithm murder mystery:
Enjoy!

Help! My son was doing fine in math until he started long division, but now he’s completely lost! I always got confused with all those steps myself. How can I explain it to him?
Long division. It’s one of the scariest of the Math Monsters, those tough topics of upper-elementary and middle school mathematics. Of all the topics that come up on homeschool math forums, perhaps only one (“How can I get my child to learn the math facts?”) causes parents more anxiety.
Most of the “helpful advice” I’ve seen focuses on mnemonics (“Dad/Mother/Sister/Brother” to remember the steps: Divide, Multiply, Subtract, Bring down) or drafting (turn your notebook paper sideways and use the lines to keep your columns straight).
I worry that parents are too focused on their child mastering the algorithm, learning to follow the procedure, rather than on truly understanding what is happening in long division.
An algorithm is simply a step-by-step recipe for doing a mathematical calculation. But WHY does the algorithm work? If our students could understand the reason for the steps, they wouldn’t have to work so hard on memory tricks.

Meanwhile, April is Mathematics Awareness Month, and this year the focus is on sports. The MAM website features articles, activities, and posters for your classroom. In addition, the ever-helpful Sravani has collected an extensive set of links for your browsing pleasure.
I finally get it — you don’t have to worry about memorizing a bunch of formulas if you just understand where they come from. You can always figure them out again.

Teaching any subject has a funny way of educating the teacher at least as much as the student.

How I Became a Better Writer Thanks to Distracted, Hungover College Kids
We all know it already, but I like the way he said it, and the blog post is worth reading. I wish this guy was teaching my college kids. Heck, my college kids wish he was teaching them — or at least, they wish that their teachers valued tight writing and would “coat undergraduate papers in ink.”

Welcome to the Math Teachers At Play blog carnival — which is not just for math teachers! If you like to learn new things and play around with ideas, you are sure to find something of interest. Let’s start the mathematical fun with an arithmetic card game in honor of our 24th edition and a few number puzzles:
