What this planet teaches

Needs vs. Wants

Every purchase falls into one of two categories:


Needs: Things you must have to live and function

  • Food, water, shelter
  • Basic clothing
  • School supplies
  • Medicine

  • Wants: Things you'd like to have but can survive without

  • Video games, toys
  • Name-brand clothes
  • Candy and snacks
  • Entertainment

  • The tricky part: Some things blur the line. You need shoes (need), but do you need the $150 Jordans (want)? You need to eat (need), but do you need to eat out at a restaurant (want)?


    A smart spending test: Before buying something, ask yourself:

    1. Do I need this or want this?

    2. Will I still want this next week?

    3. Is there a cheaper option that works just as well?

    4. What am I giving up by spending this money?


    That last question is called opportunity cost — every dollar spent on one thing is a dollar you can't spend on something else.

    How a planet works

    Go through a short lesson with the KidCash mascot, three or four cards with a question to tap and reveal on each set. Last comes a three-question checkpoint: answer two correctly to clear the planet and earn the Smart Spender badge. Lesson progress stays in this browser; when a kid signs in, planet badges and any Family-plan badge rewards save to their KidCash profile.

    Land on Market Planetoid to try the lesson cards and checkpoint. This planet’s mini game is arriving soon.
