Three Money Lessons From Kids That We Need to Learn as Adults

Recently I spent an hour with a room full of kids at a summer camp, talking about money. We skipped the lecture. Instead we turned three ideas into games: spreading your money across different things, building more than one way to earn, and keeping something aside for the day the plan breaks.

What struck me was how fast they went from understanding an idea to playing it. Within minutes they were hunting for ways to make money that were not a paycheck. They cheered when a card let them invest or open a small business. And they cheered louder, which I did not expect, when they had enough set aside to give some of it away.

Those three ideas, simple enough to teach through a game before lunch, are the same three places I watch grown-up family plans come apart.

Everything in one basket

In the game, one square can take everything. One team went all in on a space travel company. It crashed, and most of the wealth they had built went with it.

Grown-ups make the same bet. It just hides better, because the square usually looks like success. If your salary, your bonus, your stock and your 401(k) all come from one company, you are on one square.

That is not a small risk. J.P. Morgan looked at every company that has passed through the Russell 3000 since 1980. More than 40% of them fell at least 70% and never recovered. Technology was among the worst.

Spreading your money out guarantees nothing. It only means one company's bad decade cannot take everything at once.

The kids learned that in about a minute. After the crash they spread their money around without being told to. They had just felt what all in actually costs.

More than one way to earn

Most households run on one paycheck. That is one square too.

The kids saw it immediately. They wanted a second way to earn, then a third.

You may have seen the claim that millionaires have seven income streams, usually credited to the IRS. I cannot find that study anywhere. The number that holds up is smaller. Tom Corley spent five years studying self-made millionaires and found 65% had three or more sources of income before their first million.

Three sources of income is a great start toward a reliable cash flow. Seven would be remarkable. Nobody needs seven to feel secure.

Building a second income is nothing like the game we played. It is slow, it is unglamorous, and it pays nothing for a long time. But I keep thinking about how many adults settle for one paycheck and quietly hope they are not next on the layoff list.

The day the plan breaks

The kids liked this game most, because it was the one where things went wrong on purpose. A car needs repairs. Someone gets sick. A week of work disappears.

The room sulked for about a second. Then they noticed their other income was still arriving, the setback got absorbed, and the mood turned right back around. That is the whole lesson, and they arrived at it on their own.

Adults are not faring as well. Bankrate's 2026 survey found that only 30% of Americans would pay a $1,000 emergency expense from savings, and a third would go into debt to cover it. The emergency is never the surprise. The surprise is how many households have quietly decided that a credit card will handle it.

Why this belongs at your kitchen table

Georgia is doing something about this. From the class of 2028, every student will need a half-credit personal finance course to graduate, and there is evidence it works: a Georgia and Texas study found credit scores rising with each cohort that took it, by nearly 27 points for the third.

The adults are moving the other way. The 2026 TIAA Institute and GFLEC index found U.S. adults answered only 47% of its personal finance questions correctly, down from the year before.

So your children may well learn this in a classroom. You almost certainly did not, and neither did I. That leaves the kitchen table as the place where a family actually settles how many squares its money sits on, how many ways it can earn, and what happens the week something breaks.

None of those are advanced questions. A room full of children worked through all three in an hour, and enjoyed it.

If you have a friend with school-age children, this one may be worth passing along. It makes for a better dinner conversation than most of what we say about money.

If you ever want to think through how your own family answers those three, I am happy to talk it through.
