We have been learning about how to use Compatible Numbers. Compatible Numbers are any two numbers which add together to make a Tidy Number (a number which ends in zero). We had to choose two Compatible Numbers and another number. Then we had to think of a word problem which used our numbers and give the problem to a buddy to solve. Mrs Ogle, our maths facilitator, said this is called 'posing problems'.
Bob, Bobby and Bobbet have Rugby collection cards. Bob has 16. Bobby has 21 and Bobbet has 14, how many do they have together. My friend Andrew did 16 + 14 = 30 30 + 21 = 51.
