PV 6 – FRIENDS OF 10 THROUGH ADDITION, SUBTRACTION AND COMMUTATIVITY – FORMAL INVESTIGATION
10 frames are introduced in Place Value 2, including What is a 10 frame? 5 in the top row? How many in the top row? and How many in the bottom row?
In Year 1, children begin to investigate Number concepts formally.
Friends of 10 are investigated through addition and commutativity, and through subtraction.
This will allow them to begin to develop the understanding that they will apply to adding and subtracting single-digit numbers bridging 10 – integrated with Addition and Subtraction 6 and Addition and Subtraction 7.
