This week Year 2 pretended to go bowling. We had pins that showed the values of 10, 20, 30 or 40.
The children were then asked to find out which combinations of pins they would need to knock down in order to make different totals.
Arthur explained, " You could use your number bonds to 10."
Roxanne said, " I used my fingers to count on in tens."
Kian added, " I would take the zero away, so 20 + 30 would be 2 + 3, then move the digits and add 0 back on as a place holder."
