Dalo
Octopus · about 5 years old
Curious, cheerful and a little cheeky. He makes honest mistakes and lets kids put him right. His special number is 8, and he counts on his legs.
"Let's find the math!"
Short maths episodes and games · ages 4–8
Kids ask why. Dalo finds the math.
Why does my mirror copy me? Why is the other line always faster? Each episode starts with a question from a child's day, names the real maths hiding inside it, and ends with a game to play.
Hello, I'm Dalo!

How it works
Watch it, then play it
One idea, two ways in. Each takes a few minutes, so it fits between dinner and bath.

Meet the gang
Dalo and his friends
Dalo does the talking. His friends answer with faces, nods and the occasional snip snip.
Pinchy
Crab · Dalo's best friend
Proud of his big claws and a bit sneaky around cookies. Quick to sulk, quicker to make up.
Snip snip!Star
Starfish · shy and sweet
Waves with one point, hugs anything she's given and does a happy spin when an answer is right.
*happy spin*Bubbles
Fish · small and speedy
Darts in, catches things and zooms off again. Never touches the sand, always trails a few bubbles.
Blub!
For parents and teachers
Real maths, named out loud
It starts with their questions
Children don't ask for counting drills. They ask why the mirror copies them and why the other queue always moves. Dalo starts there, so the maths arrives as an answer to something they already wanted to know.
It uses the proper words
Every episode says the real name of the idea: reflection symmetry, remainders, fair sharing. Children hear the words early and recognise them when they meet them again in class.
It gives you something to talk about
Each kids' episode has a grown-up partner on The Math Behind It, a channel that explains the same idea for adults. You both know the question, so you can talk it over at dinner.

I'm a mathematician and a PhD engineer. I started writing down every "why?" my son asked, and those questions became Dalo's episodes.
