Submitted by: sumana
This activity teaches your child the concept of quantity and comparing quantities.
30 - 60 months
1 - 8 tots
- 2 Bowls or trays
- Oranges, apples, pears, lemons, limes
- Carrots, Brussels sprouts, sweet peppers
- Unshelled nuts, small gourds, popped corn.
- Display like objects in bowls or on trays. Begin with two pieces of fruit in one and three in the other.
- Discuss which has more and which has less. This is quantity. Use gestures to demonstrate more or less.
- Place another piece of fruit in each bowl. Does the bowl that began with more still have more?
- 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?
- What happens when the items added are too numerous to count? Is there more by volume?
- 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?
