When I got online this morning, I discovered that Let’s Play Math had hit #1 in the UK bestseller list for Parent Participation in Education—and I missed it!
But I did get a screen shot of my book sitting pretty at #2:
Playful Math Snacks for October: Mental Math Games
My October “Let’s Play Math” newsletter went out on Wednesday afternoon to everyone who signed up for Tabletop Academy Press math updates. This month’s issue focused on playing math games with your children, and it also included the latest updates on the Let’s Play Math paperback edition (coming not quite as soon as we’d hoped).
If you didn’t see it, check your Updates or Promotions tab (in Gmail) or your Spam folder. And to make sure you get all the future newsletter, add “Denise at Tabletop Academy Press” [Tabletop Academy Press @ gmail.com] to your contacts or address book.
And if you missed this month’s edition, no worries—there will be more playful math snacks coming in November. Click the link below to sign up today, and we’ll send you our free math and writing booklets, too!
Teacher calls out numbers consecutively, starting at 0.
When a student hears their number being called they immediately raise a hand. When the teacher tags the hand, they stand up.
If more than one hand was raised, those students lose. They become your helpers, tagging raised hands.
If only one hand was raised, that child wins the round.
“Each game takes about 45 seconds,” Hamilton says. “This is part of the key to its success. Children who have not learned the art of losing are quickly thrown into another game before they have a chance to get sad.”
The experience of mathematics should be profound and beautiful. Too much of the regular K-12 mathematics experience is trite and true. Children deserve tough, beautiful puzzles.
What are the best numbers to pick? Patrick Vennebush hosted on online version of the game at his Math Jokes 4 Mathy Folks blog a few years back, though we didn’t have to bend over into rocks—which is a good thing for some of us older folks.
Interrupt your regular math programming to try this fantastic math doodling investigation!
Anna Weltman wrote a math/art book. It’s great fun for all ages, full of fantastic mathematical explorations — including spirolateral math doodles.
How to Get Started
To make a spirolateral, you first pick a short series of numbers (1, 2, 3 is a traditional first set) and an angle (90° for beginners). On graph paper, draw a straight line the length of your first number. Turn through your chosen angle, and draw the next line. Repeat turning and drawing lines, and when you get to the end of your number series, start again at the first number.
