Activity Introduction

GST16-heroQuick summary: In this sequence of lessons, teachers can guide students in preparing and launching their own 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, the class can plan and host their event with confidence.



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 scaffold assumes that teachers will lead students to host one Garage Sale event as a team at a private premises. Alternatively, teachers may elect to run a number of sales by organising students and parent helpers into groups based on where they live. Group work should involve equitable sharing of the workload wherever possible.

This lesson is the third in a series of four 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 written guidelines to complete group-based and individual tasks.
  • 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 second of two 50-60 minute lessons which focus on inspiring and equipping students to host their own Garage Sale.  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 Running a Garage Sale Planning Document 2

Extension activity: Students can use an internet search engine to research the Garage Sale Trail’s history and achievements. This information will inspire them to get involved in the project this year.  Additional extension activities are provided in the Teacher Worksheet. 

Provisions for learning support: Students needing extra support can be paired with a friend to smooth the process of working through the activities. Assign additional time for the completion of written tasks or accept oral responses in the place of written answers for selected activities.

Key words: Garage Sale Trail, consumption, waste, recycling, economics, community engagement, life cycle analysis.

Overarching  learning  goals: 

This pair of lessons helps teachers to walk students through a step-by-step procedure that will culminate in the hosting of a team-based Garage Sale 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. Teachers should decide on a suitable venue before the classroom planning begins in earnest. Teachers might choose to encourage students to donate profits from the sale to a school or community project of importance to them.

Getting organised


Take the initiative and see how well you can organise your group to take responsibility for one of the following tasks:


1. Label Your Items

As a class, decide on fair prices for each of the sale items and clearly label them. Removable stickers are good to use for this task. It is a wise idea to limit your lowest price point to 50 cents. The handling of cash and totalling of prices can be kept simple by pricing everything in whole and half dollars, with the smallest, cheapest items at 50 cents.

Use sticky labels to mark groups of items with the prices the class has decided upon. Document these prices on your price list. Cardboard or paper signs can also be laid on the table or taped onto containers.


2. Arrange Signage

Make some large signs to advertise your sale. The bigger the signs, the more easily people will be able to see them. Make sure it is fully within the boundaries of the property and not on the foo
