+ Paper size
  * Paper comes in different sizes. There are names for the different sizes of paper. In different parts of the world, different sizes and names are used.
  * People write on paper, and books are made of paper. Paper can absorb liquids such as water, so people can clean things with paper.
+ Paper, History of paper, Machine-made paper: Writing tools
  * Today, some of the largest paper-producing countries are USA, Canada, Finland, Sweden and Russia. Paper is produced in large factories called 'paper mills'. They produce hundreds of thousands of tons of paper each year
  - Uses of paper
  * Paper is used for writing and printing. Books, magazines and newspapers are printed on paper
+ Rock, paper, scissors
  * Paper is represented by an open hand.
+ Wood
  * Wood' is the main substance in trees. Wood is used for construction of buildings or furniture, and also for art. It is also used for making fires and heating. Paper is made from wood fibres.
  * Wood can be turned into paper in large factories called 'paper mills'. The wood is first chopped into small chips and cooked with chemicals in large vessels. The chemicals separate a substance called 'cellulose' off the wood. The cellulose is then added with other chemicals and additives, and pressed into paper in large machines called 'paper machines'. Most paper is made from pine, spruce and eucalyptus.
