Sur les blogs — les derniers billets des blogs de mathématiques

I would like to start this post with a thank you to members of this site for making both this blog and inquiries.link more sustainable. I've been asked about some of the toys I've made for interactive math play. I implement them on a site

Math is wonderful, and there are so many different ways to play and experience it. I enjoy having conversations with other math lovers and sharing ideas, puzzles, pedagogy, and questions. In one of these conversations with Dr. Maria at Natural Math, I learned about a book called Modultown by Drs.

IntroductionIn this inquiry, we build a sequence from a single 2. The first rule of this sequence is that it has to describe itself.Starting with TwoHere is a 2. 2It says, "There are two here." The first number is a 2, so the next

Let me tell you about a language. But if you wish to go play instead go here. It's going to get a little abstract below.There is a Canvas to Compose UponThe canvas is a square with the largest circle that has a radius of ρ.There

Welcome to the 252nd Carnival of Mathematics! This post brings together submissions and other posts from the mathy web. Thanks all for participating.Let's start with the number: 252Divisors: 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

Thanks to Sam Graf for introducing me to this and suggesting some toys. IntroductionMultiplication tables can be fun. Line up your numbers, multiply, and find patterns. Like with 5x5, we can fill it out and highlight symmetry, divisibility, squares, and so much more. In this inquiry, we're

IntroductionPentominoes are shapes made from 5 squares joined edge-to-edge. There are 12 of them:Next, let's define what an enclosed area is with these shapes. The pentominoes must create a fence where they touch edge-to-edge with no overlaps. Note that corners touching is

IntroductionLet's start with E. Its opposite is O. So if we flip E, we get O. Let's make a pattern. EE OE O O EE O O E O E E OHow is this pattern constructed? What comes next? Write
