ACTIVITY

How many pieces of clothes do you use?

The students log how many pieces they wear and how many they have not worn in a year.

The intention is to get an overview of pieces of clothing that are, and aren’t being used.

1

Explain that this is a personal reflection on how much of our clothing we truly use. The goal: find out what you wear most often, what you haven’t worn in a year, and why. Emphasize honesty, it’s not a test, just self-awareness.

2

Over the week, students go through all their clothes at home and record them in a data log (template provided below).


For each item, they note:

  • Type of clothing (e.g., jeans, hoodie, shirt)
  • Worn in the past year? (Yes/No)
  • Approx. number of times worn (optional)
  • Comments / Why not worn (too small, out of style, seasonal, etc.)

Example table:

Clothing item Worn in past year (Y/N) Times worn Reason not worn / comment
Jeans Y 20 Everyday use
Jacket N 0 Out of fashion
Dress N 0 Special occasion only
3

After logging, students make a frequency table showing:

  • Total number of clothing items.
  • Number worn in the past year.
  • Number not worn in the past year.

Calculate percentages:

  • % worn = (items worn ÷ total) × 100
  • % not worn = (items not worn ÷ total) × 100

Using the Talking Stick method, students reflect in groups on their findings.

  • Why are some clothes not being worn? (fit, style, season, emotional reasons, forgotten?)
  • What types of clothes are worn the most?
  • What could you do with unused clothes (swap, donate, repair)?
5

Students share their findings using the 3-Point Presentation method, and through making a short presentation or poster. Include:

  • A small chart or table of their results.
  • 1–2 key insights (e.g., “I realized I only wear 40% of my clothes regularly.”).
  • 1 idea for change (e.g., “Try a clothing swap or capsule wardrobe.”).
6

Students share findings and compare patterns:

  • Who wears most of their clothes regularly?
  • Are there common reasons for unworn clothes?
  • How might this relate to consumption habits and sustainability?

Didactic tips:

  • Logging the clothing can be homework.
  • Math link: Create a class bar chart showing total % of unused clothes.
  • Follow-up: Try wearing or reusing one forgotten piece each week for a month.
  • Sustainability focus: Estimate the environmental impact of unused clothes (waste, storage, production energy).
