Not Enough for Everyone: Limited Resources
Discover why we cannot have everything we want. We will explore the idea of scarcity, which means that resources like time, money, and materials are limited.
TL;DR:Have you ever had to choose between two things you really wanted at the shops? This topic helps us understand why we can't have everything by exploring the big idea of limited resources.
About This Topic
This topic introduces Year 3 students to the foundational economic concept of scarcity, directly addressing the Australian Curriculum: HASS content description ACHASSK070, which focuses on the difference between needs and wants and the necessity of making choices with limited resources. The learning is designed to be highly relatable, using students' own experiences at home, school, and within their community as a starting point. By exploring tangible examples like pocket money, classroom supplies, and natural resources such as water, students begin to grasp that resources are finite and that this limitation necessitates decision-making.
The activities encourage students to differentiate between what is essential for survival (needs) and what is simply desired (wants). This lays the groundwork for understanding more complex economic principles in later years, such as opportunity cost, resource allocation, and sustainability. The focus is on developing economic reasoning skills through practical scenarios, helping students to see that economics is not just about money, but about how we manage and distribute all types of limited resources to meet our needs and wants as individuals and as a society.
Key Questions
- Explain what might happen if a resource, like fresh water, became very scarce in our community.
- Identify two resources you use every day that are limited.
- Analyse why money is considered a limited resource for families and schools.
Learning Objectives
- Define scarcity as the problem of having limited resources and unlimited wants.
- Differentiate between personal needs and wants using clear examples.
- Explain why individuals and groups must make choices about how to use resources.
- Identify examples of limited resources in their home, school, and community.
- Analyse the potential consequences of a resource becoming scarce.

Watch Out for These Misconceptions
Common MisconceptionIf I really want something, it must be a need.
What to Teach Instead
A 'need' is something essential for us to survive, like food, clean water, and a safe place to live. A 'want' is something we would like to have but could live without, such as a new toy or a lolly.
Common MisconceptionThere is an endless supply of everything, like water from the tap or paper for drawing.
What to Teach Instead
Many resources we use are limited. The water in our dams can get low during a drought, and paper comes from trees, which take a long time to grow. We need to use these resources carefully.
Common MisconceptionMoney isn't a real resource because we can just print more.
What to Teach Instead
Families, schools, and even countries have a limited amount of money, called a budget. If more money was simply printed, things in shops would become more expensive, so the new money wouldn't be able to buy as much.
Active Learning Ideas

The Classroom Shop
Set up a mock shop with desirable items like special stationery, stickers, or free time vouchers. Give each student a limited budget of 'class cash' to spend, forcing them to make choices as they cannot afford everything they want.
Think-Pair-Share
Desert Island Survival
In small groups, students imagine they are stranded on a desert island. They are given a list of 15 items but can only choose five to take, compelling them to prioritise needs over wants for survival.
Think-Pair-Share
Needs and Wants Collage
Students use magazines and catalogues to cut out pictures of various items. They then sort and paste them onto a large sheet of paper, divided into a 'Needs' column and a 'Wants' column.
Real-World Connections
- Discussing the family shopping list and budget before going to the supermarket.
- Understanding why the school needs to fundraise to buy new library books or sports equipment.
- Learning about water restrictions during droughts in many Australian towns and cities.
- Seeing how charities like Foodbank Australia help people who lack the resources to meet their basic need for food.
- Choosing how to spend their own pocket money or birthday money.
Assessment Ideas
Use a think-pair-share activity where students identify a limited resource in the classroom and explain a choice that has to be made because of it.
Students draw or write a short story about a character who has to make a difficult choice between two wants because they only have enough money for one.
Students complete an exit ticket at the end of a lesson, listing one need, one want, and one limited resource they encountered during their day.
