Imagine you earn 10 crisp dollar bills for walking your neighbor's dog. But when you look in your wallet, you only get to keep 8 dollars!

Where did those 2 missing dollars go, and why didn't you keep all 10?

What do we call the total pile of money you earned before anything disappears?

**Gross pay** is the total amount of money you earn from a job before any money is taken away.

If you make $10 by washing a car, your gross pay is the full $10.

So why can't you always take that whole pile of money home?

**Deductions** are portions taken away from total earnings for contributions such as taxes, community services, or savings pots ($	ext{Deductions} = 	ext{Amount Taken Out}$).

Taxes are shared money that helps build neighborhood playgrounds, fix roads, and support firefighters.

If 2 dollars are taken out of your 10 dollars for taxes, those 2 dollars are your deductions.

Once those deductions are taken away, what happens to the money that is left over?

**Net pay** is your take-home pay, which is the exact amount of money you actually get to keep in your pocket.

You can find your net pay with a simple math equation: gross pay minus deductions equals net pay ($$10 - 2 = 8$$).

Whenever you look at a paycheck or plan your savings, always check your net pay so you know exactly how much you have to spend.

Teaching the abstract financial concept of Gross vs. Net Pay to Early Level / P1 learners (ages 4–6) requires grounding in concrete, manipulatives-based learning (CPA approach). Use token economies, play coins, and story-based contexts (e.g., classroom chores or community gardens) where children earn a physical pile of tokens (Gross), place a portion into a shared community pot (Deduction), and count the remaining tokens they keep in their wallet (Net). This builds foundational schema for Scotland's Curriculum for Excellence budgeting benchmark (MNU 3-09b).
