Why Do Kids Have to Learn Things Before School Teaches Them? A Teacher Explains the Preview Problem
The question came near the end of parent-teacher conferences, after most of the folders were closed. A father named Dan sat down with a crumpled schedule and asked, “My son is in fifth grade. Every time you start a new science unit, he’s lost for two weeks. So we end up having to study it at home before you teach it. Isn’t that your job? To teach him enough to know it?”
Good question. I didn’t have a good answer at that moment. I said something about “previewing” and “building background,” but the words sounded like a way of avoiding the real issue. Dan just nodded and folded the schedule into his pocket. On the way home, I kept turning it over.
The honest answer is more complicated than a yes or no. School is supposed to teach children what they don’t know. But lessons are not long enough, and the classroom is not quiet enough, for every child to meet completely new material and succeed on the first try. For some kids, that works. They hear a new concept, they connect it to something they read or saw, and it sticks. For other kids, a new lesson is like being handed a stack of cards that all look the same. They don’t have enough small hooks in their memory to hang the new facts on. The first lesson isn’t the learning moment. It’s the moment they realize they’re already behind.
I know because I was that kid. In middle school, algebra took forever to make sense. The teacher stood at the board and said “solve for x,” and I was still trying to figure out what x was supposed to represent. She was teaching. I was listening. But all that arrived in my brain was a letter. Then came “distribute,” “combine like terms,” “inverse operations.” I didn’t need a different teacher. I needed to have seen the idea before, just once, so that when it was formally explained, it had somewhere to land.
That’s why I began asking parents to do something that looks like homework but really isn’t. I send home a one-line note on Friday: “Next week in social studies: the Louisiana Purchase.” That’s it. No questions. No worksheet. I ask families to talk about it at dinner, or leave a library book out, or find a short video about the subject. The child doesn’t need to learn it. They just need to recognize it.
The difference matters. If I teach a unit on the water cycle and a child has never heard the word “evaporation,” the class discussion might as well be in a foreign language. But if that child has seen a puddle dry on the sidewalk and heard a parent say “it evaporated,” then when I write “evaporation” on the board, the child thinks, Oh, that thing. And the rest of the lesson can follow. The prior knowledge doesn’t have to be academic. It just has to exist.
This is not “learning in advance.” It’s a kind of preparation that happens outside school all the time for kids who grow up around a lot of words. A family visiting a science museum on a weekend teaches a child about fossils without meaning to. Another child listens to grandparents talk about soil and rainfall and comes to class knowing more about erosion than she realizes. The school still does its job—explaining, expanding, connecting—but the child walks in with something on the line. The lesson has somewhere to attach.
Parents often hear “preview” and think they’re now responsible for teaching the whole curriculum. That’s not what I mean, and it’s not what most teachers mean either. Previewing is a low-stakes look at a topic, not a trial run. It shouldn’t create pressure. If your child doesn’t understand the preview, that’s fine. The goal is just to make the material familiar enough that she doesn’t panic when it shows up in a lesson.
The specific actions are simple. On Friday, ask the teacher: “What are you starting next week?” Then choose one small way to bring it up. Put a sticky note on the fridge. Ask the child if she’s heard an unusual word. Get a picture book from the library. If the topic is fractions, point at a measuring cup while you’re baking. If the topic is ancient Egypt, find a documentary trailer online. It doesn’t have to be a lesson. It’s a passing glance. The point is to make sure that when the teacher begins, the child isn’t meeting the topic for the very first time.
I eventually told Dan something closer to that. I admitted that yes, it is a school’s job to teach. And I said that a child who has never seen even a shadow of the topic has to build a whole framework on the spot while the rest of the class is already taking notes. That’s a harder job than school, on its own, can always fix. A little previewing doesn’t replace teaching. It clears a path so the teaching can actually reach him.
Later that week, Dan sent an email asking what was coming in math. I sent the next unit title: decimals. No explanation. He wrote back, “So I should just mention what a decimal is when we’re at the store?” I said that was enough. I don’t know whether his son later became an expert in decimals, or whether Dan still wonders if this is fair. Sometimes I still wonder too. But I’ve seen what happens when a child walks into a classroom already having walked past the door once before. School isn’t supposed to be a room with no door. It’s supposed to be where the walking goes deeper.
