Cass

Cass reached out and tapped the top line of the framed card.

"Question one," Cass said. "Before anything else, what do we actually know?"

"Don't try to solve it yet," Cass added. "Don't look at the question mark at the end. Just tell me one fact."

The kid squinted at the paper. "The tank holds five hundred gallons."

"Good," Cass said. "That's one. What else?"

"Pipe A fills it at twenty gallons a minute."

"Two," Cass said. "Keep going."

"Pipe B drains it at twelve gallons a minute. And it starts half full."

"Four facts," Cass said, taking a blue index card from a box on the table and laying it down. "Look at that. You went from zero facts to four facts in thirty seconds."

The kid looked at the four facts written on the card. The tight, defensive knot between his eyebrows smoothed out just a fraction.

Panic was a noisy thing. It filled a person's ears with buzzing until they couldn't hear the problem at all. Listing facts was like turning down the volume knob on a loud radio. Anyone could list a fact. It didn't take a genius; it just took eyes.

Cass knew all about the noise.

Years ago, long before the workshop existed, young Cass had been a world-class freezer. Back then, a word problem wasn't a puzzle. It felt like a personal attack. Cass remembered sitting at a battered school desk while the wall clock ticked like a judge's gavel. Other kids' pencils were already scratching across their paper, quick and confident. Cass had sat motionless, staring at a problem about train schedules, convinced that a wall had dropped in front of the page.

In those days, young Cass believed in a secret. The secret was that some people were born with a special organ inside their skulls—a math brain. It was smooth and fast, like an engine that never stalled. Cass assumed their own brain was made of wet cardboard.

Then an old teacher named Mr. Abernathy had walked down the aisle. He hadn't handed Cass an answer key. He had sat down, smelling faintly of pipe tobacco and peppermint, and looked at Cass's blank sheet.

"You think you're stuck because you're slow," Mr. Abernathy had said in a quiet voice.

Young Cass had nodded, eyes fixed on the desk.

"You're not slow," the old man said. "You're just trying to finish before you start."

"Not knowing where to start isn't a flaw," he said. "It's the normal, universal first feeling of every hard problem—for everyone."

"The people who look fast don't have a better brain," Mr. Abernathy added. "They just have a routine for that feeling."

Mr. Abernathy had written four questions on the margin of Cass's paper.

That afternoon, the magic wasn't that the questions solved the problem instantly. The magic was what they did to the feeling inside Cass's chest. "I'm hopeless" became "I'm on step one." The cardboard brain vanished. In its place was simply a staircase, wide enough for anyone to walk up if they took one step at a time.

Back in the workshop, the kid tapped his pencil against the blue card.

"Okay," the kid said. "So we know what we have. But I still have to figure out how long it takes to fill up."

"Which brings us to question two," Cass said, pointing to the second line on the frame. "What's our plan?"

The kid leaned back, looking around the room. Through the glass partition, they could see the rest of the workshop bustling with activity.

Over by the high tables, Reck was squinting at a giant wooden balance, making big, wild estimates with his hands. In the corner, Lettie was sketching clean, elegant symbols on a slate board, lining up equal signs like soldiers. Kindra sat near the sorting bins, grouping colored wooden blocks into tidy piles by shape and pattern. Near the window, Vetta was holding up a finished bridge model, stress-testing every joint with a brass gauge.

"You've met them all today, haven't you?" Cass asked softly.

"Yeah," the kid said. "Reck told me to guess first. Lettie wanted me to write an equation with $x$."

"Kindra told me to sort the numbers," he added. "And Vetta made me check my work twice before I even finished."

He paused, rubbing his forehead. "It's a lot of ways to do things."

"They're not different subjects," Cass said. "They're just different stepping stones across the same river."

"When you're stuck, Reck gives you a rough bank to jump toward," Cass explained. "Kindra helps you group the rocks so you don't trip."

"Lettie gives you a sturdy plank to walk across. And Vetta makes sure the plank isn't rotten before you step on it."

Cass tapped the framed card again.

"Here is what ties them all together," Cass said. "Every single tool in this room is designed for one moment: the moment you don't know the way in."

"And not knowing the way in is where everybody starts," Cass said. "Not just you. Everybody."

"The trick isn't never being stuck," Cass added gently. "The trick is having calm questions to ask when you are."

The kid looked down at his paper. The water tank problem hadn't grown any shorter. The numbers were still the same. But the room felt slightly larger, as if someone had opened a window and let out the stale air.

"I always feel like I'm supposed to know right away," the kid admitted. His voice was lower now, free of the defensive edge it had carried five minutes ago. "When the teacher finishes reading the problem, three kids put their hands up. I feel like my brain just turns off."

"That feeling isn't a verdict," Cass said warmly. "It's just step zero."

"Step zero?"

"Step zero is standing on the bank, looking at the water," Cass said. "It's fine to stand there. It's where everyone begins."
