Advance Preparation
For Penny Plate in Part 2, obtain paper plates or other open-top, opaque containers. During the game, children
will turn the containers upside down and arrange as many as 20 pennies on the containers' bottoms. Make sure
the bottom of each container is wide and sturdy enough to hold the pennies.

Algebraic Thinking Have children read the rules for Penny Plate
on pages 146 and 147 in My Reference Book and play the game in
partnerships. Playing this game frequently will help develop
children's automaticity with sum-equals-ten facts.
Ongoing Assessment: Informing Instruction
Watch for children who are having difficulty determining the number of pennies.
Suggest that they draw circles to represent all of the pennies. Then suggest that
the children use one of the strategies below to figure out how many pennies are
under the plate:
Children name the two parts of 10 shown here: Cross off one circle for each penny on top of the plate. Count the uncrossed
6 and 4. circles to find the number of pennies under the plate.
Use a second set of pennies as markers. Cover one circle for each penny on
top of the plate. Count the uncovered circles to find the number of pennies
under the plate.

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
