problem solving

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'.

Andrew like cars he had three boxes of cars in one he had 14 in the other he had 16 cars and last he had eight cars how many does Andrew have all together?

10+10=20

4+6=10

20+10=30

30+8=38
