Supply and demand (simple)
Supply is how much exists; demand is how much people want.
In this lesson
Supply and demand (simple) is part of Money Has Value. This preview shows how money-fundamentals connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.
Today’s money mission
DeeDee sees a real money moment: A mango seller has 200 mangoes but only 5 people want to buy today. What should the seller do to sell them all? Before choosing an answer, slow down and find the money action in the story.
What you need to know
Supply is how much exists; demand is how much people want. The key is to ask what is being traded, earned, spent, saved, trusted, or recorded. Once you find that action, the lesson becomes easier: the right choice should match the money rule, not just the loudest feeling or fastest option.
Real-life example
For example, if a child sees a price, a balance, a goal, or a task reward, they should ask: what changed, who gave something up, and what should the account record show next?
Progress Penguin connection
