Modeling and Recording Addition: Tips and Tricks

  • Use a variety of classroom objects as manipulatives. Let children use crayons, paper clips, books, and so on.
  • Make your own manipulatives by cutting out, or having children cut out, pictures from magazines and laminating them. Or have children draw a picture of a single item, such as an insect, a bird, or a tree. Then copy and laminate the drawings for use as manipulatives.
  • Use Workmat 2 in the pupil book, with spaces for counters or other manipulatives. These mats can be duplicated for children to write on with pencil or crayon, or laminated so children can write with washable markers.
  • Have children draw “background” pictures upon which addition stories can be modeled by using counters. Backgrounds might include a tree, a park, a garden, a house, or a playground.
  • Have the class sing “I Know an Old Lady Who Swallowed a Fly.” Put up pictures of each animal as it is swallowed. From time to time, stop the song and ask the children to count the number of animals. Then ask how many animals the old lady will have swallowed when she swallows 1 or 2 more.
  • Have children illustrate double facts by folding a piece of paper in half and then painting up to 5 dots or shapes on one side. Then have them refold the paper along the same line so the paint is transferred to the other side.
  • Give children a small cup and up to 10 beans that have one side painted red. Have children turn the cup over so that the beans spill onto a desk. Then have children write addition sentences in which one addend is the number of red beans and the other is the number of nonred beans. Vary the number of beans to reinforce different sums.
