AcknowledgementThis activity derived from a discussion between Jenni Koehler, Rohan Perrot (Chillwell Primary School), Henya Worland (Nelson Park Primary School) and Doug. Williams (Session Leader) at a presentation of the Maths on the Move professional development day titled Engineering 'aha' Moments in Number.
Player A now rolls again and adds more yellow plugs to their board. If their total is now ten or more, 10 plugs are exchanged for a blue which is placed on the other side of the board. For some children it might be necessary as a transitional step to fill the board and complete adding yellow plugs outside the board before the exchange is made. When the exchange (if it is necessary) has been completed, Player A begins a running record of the addition on their calculator by recording the new amount added. So, if 6 was rolled following the turn above that produced 5, Player A would now press [+] [6] [=] and the screen would show 11. Note: Using the calculator provides a visual link between the symbolic representation on its screen, the kinaesthetic action of placing the plugs and current number of tens and ones.Player B now has their second turn and play continues in this manner until the chosen number of tens is reached or exceeded.
Tens Only VersionIn this version, only one Poly Plug is needed per pair. Children work together to collect ten red plugs on the 'possy mat'. As the game proceeds, the red plugs removed to make the 10 frame will be used to record tens on the 'possy mat'.The children begin by playing Ten Friends and when the frame is filled they place a red plug on the 'possy mat' to record it. They say to each other: We made ten. They can also keep a running record on the calculator using addition. Players swap roles and play Ten Friends again. This time when they transfer their red plug to the 'possy mat' they say to each other: We made ten more. Ten and ten make twenty, and touch the red plugs as they say it. So, after two frames, the children would see:
The game continues in this way as far as the children can take it, but, eventually - and very soon for some children - until they can say (and touch): Variations
