A mi m’ha fet pensar amb els #explodingDots
Division made easy🤩
Vamos a probar otras máquinas.
Además, con números grandes el sistema con puntos se hace "engorroso".
¿Podéis encontrar una forma más rápida de utilizarlas?
¿Qué observáis? ¿Cómo funcionan en realidad?

Comenzamos con los #ExplodingDots de @jamestanton.
¿Cómo se representan estos números en la "máquina 1<--2"?
La secuencia completa (hasta operaciones con polinomios en Secundaria), aquí: https://t.co/zyisWBHyoB
In base 10, a number is divisibly by 2 if the last digit is even. It is divisible by 3 if the digit sum is divisible by 3. Etc.
What would the rules look like for hexadecimal (base 16)?

El pasado 21 de marzo presentamos los resultados del Estudio MAPS, una investigación sobre el impacto de #ExplodingDots en el aprendizaje matemático.
🎙️ Hoy, para seguir explorando su alcance, hablamos con @jamestanton, creador de Exploding Dots, sobre su visión sobre la innovación en las matemáticas.

The number ten can be written as a palindrome in a base-ten #explodingdots way, but it uses negative "digits."
Can ten be written as a palindrome avoiding negative numbers?
Which two-digit numbers are exploding-dots-palindromes with positive digits?
Can every number be written as a palindrome in some #explodingdots way?
(For instance, 21 equals one 100, negative eight 10s, and one 1.)
For a number N, let N* represent the number with its digits reversed.
If a is a palindrome, prove that it is possible to write N in an #explodingdots way so that
a x N* = (a x N)*
(The product of a palindrome with a number and with its reverse are also reverses.)
Multiply a number and its reverse by 81.
Prove that the two products can be written in an #explodingdots way so that they are the reverse of each other!
What a fabulous lad ... and fabulous Dad for allowing the true fun of learning thrive!
And gotta love them dots!

“Follow the child” can be as easy as helping them go down the rabbit holes of their own choosing.
6yo wanted to know how computers worked so we did some research. He was curios about binary so we pulled up Exploding Dots by @jamestanton.
In <1h he was converting binary to decimal.
