01 Opening
Sortle beat 1 of 5

Sortle is a bright-eyed magpie-kid who loves tidy things arranged just so. Sortle lives among rows of little bins in the Shape-Workshop, always ready to turn a messy heap of shapes into neat, sorted groups.

Sortle does one satisfying thing: Sortle picks one rule and sorts everything by it. "Today we sort by color," Sortle chirps — and every red shape goes in the red bin, every blue in the blue bin. Or, "Today we sort by shape," and all the circles gather together, all the squares together. The trick is picking the rule first, then following it every time. "One rule at a time," Sortle says, hopping between bins. "Pick the rule. Then sort by it."

02 Sortle
Sortle beat 2 of 5

Sortle learned sorting after a very muddled pile.

When Sortle was little, Sortle tried to sort by everything at once — color AND shape AND size — and it turned into a hopeless jumble, with a red circle unsure whether it belonged in the "red" pile or the "circle" pile or the "small" pile. So confusing! Then Sortle learned the calm way: choose just ONE rule. Sort by color today — never mind shape or size. Suddenly every shape knew exactly where to go. "One rule," Sortle learned, "and the pile sorts itself."

Sortle beat 3 of 5

Today, Poly brings the kid over to Sortle's bins. "Sortle sorts things into neat groups," Poly says. "Watch how Sortle picks one rule."

"Sort with me," Sortle says, eyes bright. "First we pick the rule — color? shape? size? Then every shape goes to its bin by that one rule."

04 Sortle
Sortle beat 4 of 5

Sortle shows the kid a heap of mixed shapes. "Let's sort by shape today," Sortle says. Every circle goes in one bin, every triangle in another. A grown-up can sort along too: pick a rule together, then take turns placing shapes — because sorting is for tidying together, never a test. And Sortle never says "wrong." If the kid puts a triangle in the circle bin, Sortle hops over kindly: "Ooh — our rule is shape. Is this a circle? Let's feel its corners. Three corners — that's our triangle bin!" In Sortle's rows of bins, every misplaced shape just gets a gentle second look at the rule.

05 Closing
Sortle beat 5 of 5

By the end, the kid has sorted a whole messy heap by shape, then by color, all by themselves. Sortle's feathers gleam with pride.

And here is what Sortle loves most: the deeply satisfying feeling of a big messy pile becoming neat, sorted groups — that calm, ordered, "ahh, everything's in its place" feeling. Sortle feels it settle warm every time the last shape finds its bin. "One rule, and the pile sorts itself," Sortle says happily, tucking into a tidy little nest. That calm, tidy feeling of everything-in-its-place — that's the very best part for Sortle.

Reading together with a grown-up? A card for the grown-up

For the grown-up: ask one question, then wait. When they answer, add one word to what they said. Tap the button when they have said something — that is one turn each, a circle. Nothing is recorded or kept.

Let them finish it

Say “Sortle sorts by ONE thing at a time — shape, or …” and stop. Let them finish it.

Then say the whole line together: “Sortle sorts by ONE thing at a time — shape, or color, or size — that's fine!”.

Now wait. Count slowly to five in your head. Their answer is worth the quiet.

Circles together: 0
