Supplies

  • 2 Bowls or trays
  • Oranges, apples, pears, lemons, limes
  • Carrots, Brussels sprouts, sweet peppers
  • Unshelled nuts, small gourds, popped corn.

Steps

  1. Display like objects in bowls or on trays. Begin with two pieces of fruit in one and three in the other.
  2. Discuss which has more and which has less. This is quantity. Use gestures to demonstrate more or less.
  3. Place another piece of fruit in each bowl. Does the bowl that began with more still have more?
  4. Continue with a different set of objects. What happens when two are added to the bowl with less, and one is added to the bowl with more. Are they now the same?
  5. What happens when the items added are too numerous to count? Is there more by volume?
  6. What happens if the items are spread over a larger surface? Are there still fewer nuts on the second tray if they take up more space?
