vegetable soup

  • Introduce the children to the concept of 1 more.
  • Show them a real or paper soup pot.
  • Pretend to be Chef Peter Rabbit. Put 1 paper vegetable into the pot, and say, "There's 1 carrot in the soup." Ask, "Who can add 1 more?" Select a child to put in 1 more and say, "1 more makes ____________." (Have children help you complete the sentences.)
  • Complete the demonstration by saying, "Now there are 2 carrots in the soup." Start with 1, 2, or 3 vegetables and play "Add 1 More" with the children.


  • Help children play "Add 1 More." Children should take turns being Chef Peter. Peter puts some vegetables in the pot and says, "There are vegetables in the soup." Who can add 1 more?
  • Peter chooses another child to add the vegetable and says, 1 more makes. Now there are vegetables in the soup.
  • Encourage children to explore putting larger numbers in the pot and adding 1 more or 2 more.
Children work in pairs to play "Chef and Helper." The Chef puts some vegetables in the soup and says, "There are _________ vegetables in the soup. Who can add 1 more?" Helper puts a vegetable in the soup and says, "Now there are vegetables in the soup." Then they reverse roles.
