Income vs. Expense Sorting Cards
Income is money that comes in. An expense is money that goes out to buy or pay for something. Sort 48 everyday money events — chores, birthday money, a lemonade stand, the book fair — and find the third pile most lessons never mention: the money that only moves, like cash you put into savings or the change you get back.
How It Works
One question, forty-eight little stories
Every card is one thing that happened to a kid’s money, and students ask one question: which way did the money go? “You walk the neighbors’ dog and they pay you $8” is income. “You pay $4 for lunch in the cafeteria” is an expense. And “you move $10 from your wallet into your piggy bank” is neither — you have exactly as much money as before. Print once on cardstock and it is a station you can reuse all year.
Sort in vs. out
Start with two mats and the first 12 cards. Money that came in to you is income. Money that went out to buy or pay for something is an expense. Students place each card, then say how they know.
Add the “neither” mat
The surprise. Putting money in savings, taking it back out, getting change, getting a refund — the money moved but you are no richer and no poorer. This is where “money I moved is money I made” falls apart.
Add it up
Turn the sort into math. On the Money In, Money Out sheet students total one week of income, total their expenses, subtract, and see what is left — with a separate box for the money that only moved.
What’s Inside
Twenty-two pages, from card sort to what’s left
- 48 sorting cards — 18 income, 18 expense, 12 that are neither. Eight per page with dashed cut lines, and every sheet mixes all three piles.
- Three sorting mats — Income, Expenses, and Neither, one full page each.
- Three anchor-chart posters — Income, Expenses, and a side-by-side comparison with the money-flow formula.
- A Money In, Money Out worksheet — total one week in, total one week out, subtract, and find what is left.
- A student recording sheet — write-in columns plus a Neither section for money that only moved.
- A teacher answer & discussion key — every card with a reason, plus notes on the verb trap, the same-money trap, and the object trap.
- A three-page teacher guide — objective, materials, how to use it, how to differentiate grades 2 through 5, and a page on what students will try instead of reading.
- An extension page and a low-ink version — deeper writing prompts, and the whole pack again in clean black and white.
Why These Cards
“I put $10 in savings, so I made $10”
That sentence is the reason this deck has a third pile. To a child, money arriving in the piggy bank feels like earning, and $3 of change handed back at the register feels like a little gift. Neither is true: both are money they already had, in a new place or on its way home. Until a student can see that, adding up a week of money will always come out wrong.
So the deck is built so the answer can never be guessed. The same $20 is income when Grandma gives it and neither when it moves into savings — you do not earn it twice. A bike shows up in all three piles. And the word at the front of the card is no help at all: “pay” is income on the cards where someone pays you, “put” is an expense into a vending machine and neither into a savings account, and “get” lands in every pile there is.
Even the feeling is a trap we designed out. Doing chores all week and cleaning out a neighbor’s garage are income; buying your sister a birthday present and giving to the food drive are expenses. A student sorting by whether the card sounds happy will get those wrong — which is exactly the conversation worth having.

Keep Going
What to teach around the sort
These cards are the hands-on way in. Once students can say which way the money went without hesitating, move them to the lesson that goes deeper and to the companion card sorts.
What Are Income and Expenses?
The video lesson and quiz that go deeper, for older students. Sort the cards first, then watch it — the vocabulary is already in their hands.
Needs vs. Wants Sorting Cards
The natural next sort. Once students can spot an expense, the question becomes which expenses they actually need. Same format, same mats, same routine.
Fixed vs. Variable Expenses
The step up for grades 3–6: now that a bill is an expense, does it cost the same every month or not? The companion deck for older students.

Questions
Before you print
What is the difference between income and an expense?
Why is there a “neither” pile?
Is saving money an expense?
Is this a budgeting worksheet?
What grades is it for?
Is the free sample actually usable?
Print it once, sort it all year
Cut the cards apart, put them in a station, and “income” and “expense” stop being two words to memorize. They become a question students answer with a card in their hand — and then add up into a week of their own money.
