Activity Introduction

GST8-heroQuick summary: In this pair of lessons, teachers can guide students in preparing and launching their Garage Sale. The activities presented here provide practical steps students can take to get involved in this year’s Garage Sale Trail event. Both the planning and operating stages of the project are covered in this resource. By following this sequential scaffold, students can plan and host their event with confidence.

GST_Logo_CMYK_High Res_STAMPThis resource assumes that students will team up with others living in their locality to host Garage Sales in groups, at private premises. Teachers may elect to organise students into groups based on where they live. One class may host a number of separate Garage Sales across multiple locations. Group work should involve equitable sharing of the workload wherever possible.  

Following this lesson plan is an ideal way for your school to take part in the Garage Sale Trail. You’ll be joining thousands of amazing teachers in making a difference and creating positive environmental change. Don’t forget to register! 


This lesson is the second in a series that are designed to:

  1. inform students about the environmental problems of wastage and over-consumption
  2. inspire and equip students to host their own Garage Sale
  3. communicate the results of their efforts to various audiences and evaluate the impact of the initiative locally and nationally

Learning goals:

  • Students follow generic written guidelines, modifying them into specific procedures to suit their individual circumstances.
  • Students estimate the value and usefulness of some of their personal possessions.
  • Students view reselling items in a Garage Sale as a proactive response to wasteful consumerism.
  • Students engage with a social and environmental issue through active participation.

Duration of activity:  This is the first of two 50-60 minute lessons which focus on the second learning objective.  Additional time outside of school hours will be needed for students to implement their planning and complete the Garage Sale project.

Resources required: Student Worksheet

Extension activity: Teachers should use their discretion to extend capable students by allocating to them more complex tasks or greater responsibilities in certain areas. 

Provisions for learning support: Teachers might consider assigning extra time for the completion of some tasks in this lesson sequence.

Key words: Garage Sale Trail, consumption, economics, community engagement, life cycle analyses.

Overarching  learning  goals: This lesson is designed to walk students through a step-by-step procedure that will culminate in the hosting a team-based Garage Sale event or their own individual event.

Note: Teachers will need to obtain permission from school authorities to proceed with the planned Garage Sale, wherever it is held. Families should be advised of preparations and permission for each student’s involvement must be documented. Schools should encourage parental helpers to become involved in the event.

GST22-heroPlanning Document 1 - Getting organised

Work through each planning point by reading and discussing them within your group. Make notes for your own reference.

  • Obtain permission

The first step in the planning process is to ask your parents or care-givers for their permission to host a garage sale. You should only sell items that are yours, obviously! But to make the garage sale a greater success, offer to sell things belonging to other people in the household for them. If you do this, ensure that you keep an accurate record of which items belong to each contributor and consult with them on pricing. You could also ask neighbours, friends and relatives if they have anything they want you to add to the stock for sale. Make sure you ask permission to sort through rooms, sheds and stored things if they are not yours.

Permissions needed: 


  • Find a suitable venue

You will need to work within your group to identify a suitable place to host your garage sale – a garage is ideal and
