Chapter 51 - The First Class He Taught
Noah's first class as a graduate teaching assistant began with a broken projector. He called me afterward, laughing at how quickly he had discovered that teaching required more than understanding the subject. The students were impatient, the room was crowded, and one question had exposed a gap in his explanation that he had never noticed when solving the problem alone.
"Did you answer it?" I asked.
"Eventually. After I admitted I had to think."
"That sounds like good teaching."
He wasn't sure. He had expected to feel confident at the board. Instead, he found himself paying attention to faces, adjusting examples, and trying to understand why students who were perfectly capable of mathematics approached the same question differently.
I thought of the tutors in our programs. The best ones didn't simply know the answer; they noticed when a child had stopped following and changed their explanation without treating the confusion as failure.
Noah asked whether he could visit one of our math workshops during break and observe. I welcomed the idea, with the understanding that he would participate as a volunteer under the program rules rather than a celebrity alumnus.
When he arrived, he watched a tutor working with a girl who believed she was terrible at mathematics because she had failed a test. The tutor asked her to explain one problem and patiently identified the step she misunderstood. Noah sat beside them and offered another example. By the end, the girl was laughing at a mistake she had made earlier.
After class, Noah looked thoughtful.
"I keep forgetting how much fear changes what people can hear," he said.
I understood. My own fear had shaped conversations with Vincent for years. It had made me interpret silence as abandonment and questions as threats. Noah's students came to the room with their own histories, smaller but no less real to them.
He returned to his university and changed how he prepared lessons. He wrote down common misunderstandings, practiced explaining concepts in ordinary language, and invited questions before students felt lost. His evaluations improved, but what mattered more was that he began enjoying the work.
Vincent attended a public teaching demonstration during a visit. He sat among other guests and watched Noah help students work through examples. Afterward, he told his son he had never realized teaching was so demanding.
"Most things are demanding when you can't delegate the difficult parts," Noah replied.
Vincent laughed. I suspect he heard the gentle criticism beneath the joke and accepted it.
At the nonprofit, our new tutors began using some of Noah's revised materials. We documented the permission and credited the contributors appropriately. I liked seeing his work travel into rooms where nobody knew the Moretti name and where the main concern was whether a child understood fractions.
One evening, Noah called to tell me a student had finally solved a difficult problem after weeks of effort. He sounded more excited than he had after receiving his own award.
"I think I understand why people teach," he said.
"Welcome to the club."
Teaching also exposed Noah to the practical problem of fairness. A student requested extra time on an assignment after missing a deadline, citing a personal emergency. Noah wanted to help but worried about treating classmates differently. He consulted the course policy and the supervising professor rather than making a private exception he couldn't explain. They granted the accommodation through the established process. The student thanked him, and Noah felt relieved.
When he described the situation, I thought about my nonprofit work. Rules were not necessarily cold. They could make kindness reliable by ensuring that a student's need did not depend entirely on whether an individual instructor happened to feel sympathetic.
A month later, Noah received mixed teaching feedback. Some students appreciated his patience; others found his explanations too fast. He was disappointed. Then he asked a colleague to observe a class and tell him what she noticed. She suggested pausing more often and inviting students to explain steps in their own words. He tried it, and the room became more engaged.
I loved hearing about his revisions. The boy who had once feared one wrong answer would reveal he wasn't as smart as everyone said was becoming a teacher who could learn openly from his students.
After the undergraduate class ended, Noah received a small card from several students thanking him for being willing to explain questions more than once. He sent me a photograph of it. I asked whether he was proud. He admitted he was. Teaching had given him a kind of satisfaction different from producing research: the result appeared in another person's confidence rather than in his own calculations.
We spoke about the tutors who had helped him as a child, some of whom still worked in the Providence library system. Noah decided to write one a letter of thanks. The teacher replied with delight and told him she'd always remembered his habit of asking what happened if the numbers changed. Noah laughed when he read it. The curiosity had been his long before anyone connected him to Vincent.
At the next class, he paused after an explanation and asked students to tell him what was confusing. More hands went up than he expected. He answered patiently. The room felt more open, and he discovered he liked the work even when nobody understood him on the first attempt.
Before the semester ended, Noah told me he had stopped asking students whether they understood everything and started asking which step had confused them. The change produced better questions and fewer embarrassed silences. He sounded delighted by the result.

The next time I visited, he showed me the classroom where he worked. There were equations on the board and half-erased notes from the previous lecture. He stood near the front, proud and a little shy.
I remembered the boy at our kitchen table who worked on equations while I calculated grocery expenses. I had wanted him to have choices. He was making them, and some were leading him toward helping others find their own.
