      Card functional properties

      Lesson details

      Learning outcome

      I can use different techniques to shape card.

      Key learning points

      1. Robert Gair devised the concept of the paperboard folding carton.
      2. Card can be shaped in different ways.
      3. Scoring before folding or cutting improves accuracy.

      Keywords

      • Packaging - material used to wrap, cover or protect a product

      • Technique - a particular way of doing something

      • Scoring - pressing a line into paper or card to help with folding and cutting

      Common misconception

      Packaging has always been the same.

      Packaging has developed over time. The rise in plastic use has seen plastic replacing glass, increased use of recycled paper/card, less use of wooden crates used in the past.

      Teacher tip

      Model scoring techniques with pupils. Use age appropriate scissors at this stage. Model the use of a safety ruler and protect surfaces.

      Equipment

      Various thicknesses of scrap card (rectangle shapes will work best), safety rulers, scissors and pencils.
