New Edition of Must-Read Math Book

Posted on by Denise Gaskins

I thought I knew math fairly well.

I thought arithmetic was boring.

I thought the reason other nations beat America in international math tests was that their students worked harder than ours.

I thought all sorts of silly things before I read Liping Ma’s Knowing and Teaching Elementary Mathematics. Now this must-read book is coming out in a new edition, due in bookstores next week.

I can hardly wait!

In American elementary mathematics education, arithmetic is viewed as negligible, sometimes even with pity and disdain—like Cinderella in her stepmother’s house. Many people seem to believe that arithmetic is only composed of a multitude of “math facts” and a handful of algorithms. . . Who would expect that the intellectual demand for learning such a subject actually is challenging and exciting?

Have a Mathy Christmas

Posted on by Denise Gaskins

A mathematical Christmas? You bet! For instance, I just noticed that Raymond Smullyan’s The Lady or the Tiger is finally back in print. My family and my math club students have enjoyed many of the puzzles in this book over the years, and I can’t think of a better stocking stuffer for the mathophile in your family.

(I do hope that means the rest of Raymond Smullyan’s puzzle books will be coming back, too!)

In the holiday gift-giving spirit, I’ve started making a list. Check out the links below for more mathematical Christmas present ideas.

More Fun with Hexa-Trex

My elementary Math Club students had fun practicing their math facts and “out of the box” thinking with Hexa-Trex puzzles. The object of Hexa-Trex is to find a path through all the number and operation tiles to make a true equation. The “Easy” puzzles are just the right level for my 4th-5th grade students, although they get stumped whenever the equations require Order of Operations. One girl enjoyed the puzzles enough to take our extra pages home for her dad.

Hexa-Trex puzzles were featured in the October issue of Games magazine, and now you can enjoy Hexa-Trex away from the computer with Bogusia Gierus‘s new book, The First Book of Hexa-Trex Puzzles. If you are thinking ahead to Christmas (can it be that time already?!), and if you have a puzzle lover in the family, this little book would make a fun stocking-stuffer.
