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'.
Mikayla had 87 toy cats and Corrin had 18 toy cats and Mrs B had 3 toy cats. How many are there altogether ?
87+3 = 90
90+18=108.
