Addition
To explore finding sums to ten using a concrete model, have
children play Two-Fisted Penny Addition. Children count out
10 pennies and split them between their two hands. Help children
identify their left and right hands.
Call on several children to share amounts. For example:
   My left hand has 1 penny and my right hand has 9 pennies.
   My left hand has 3 pennies and my right hand has 7 pennies.
The various splits can be recorded on the board.
Repeat with other numbers of pennies. Partners can continue to
practice using different total numbers of pennies: 9, 12, 20, and
so on.                                                                                                                   Game Master
