Economics and Money for Kids: What to Teach at Each Age

Money ideas can be taught from age 4 if they fit what the child lives: trading one thing for another, waiting, working and choosing. What changes with age is depth, not the topic. There are three stretches.

How to do it

Ages 4 to 6: the child learns to trade and choose. At the store, let them pick between two fruits and tell them: "If we take this one, we don't take the other." At home, sort five things from the cart together into "we need it" and "we want it."

Ages 7 to 8: they learn to compare and plan. Give them 3 dollars for the week's snack and ask them to compare two options: "Which gives you more for the same?" Have them explain why they chose.

Ages 9 to 10: they learn causes and plans. Ask why a lemonade costs more at the fair than at home, and then have them propose a three-week plan for something they want.

For all ages, one idea per month, repeated in different situations. Every three months, ask what they understand and move up a step.

What it's for

For your child, learning happens with what they already see, without feeling like a class, and they feel grown-up when they can explain something adult. For you, the doubt about whether it's too early or too late disappears: you have a map by age and a task for this week.

What the research says

Berti and Bombi, in The Child's Construction of Economics (1988), describe how children build ideas about prices, stores and work in stages, and that understanding integrates later; that's why you start with the concrete. Fletcher and Wright (2024) found that financial understanding can already be measured between ages 4 and 6. Brown, Roediger and McDaniel, in Make It Stick, show that returning to an idea with time between visits fixes it better than repeating it back to back.

What you'll see over time

In the first weeks they repeat your phrases even if the child doesn't fully understand them. Between one and six months they use it in another situation, like "if I buy this, I won't have enough." In the long run they go from "I want it" to "how much does it cost and what do I give up," and start proposing plans.

Signs it's working

You'll notice when they explain a decision in their own words, when they apply the idea to something new and when they ask "why does that cost that much?" If nothing changes, the idea probably belongs to another stage: go down a step and return to the concrete.
