**Predict:** I predict that this might have to do with problem solving because when I looked at it, the problem was lengthy.

**Read:** When Tony has his birthday tomorrow, his age in months will be the same as his grandfather’s age in years. How old will Tony be if their combined ages will be 78?

**Clarify: **I have nothing to clarify about the problem.

**What’s the BIG question? **What age will Tony turn tomorrow?** **

**Working out: **I know that there is 12 months in a year and his grandpa’s age is in Tony’s months. Firstly I knew that I will have to try some numbers and times them by 12 then takeaway the number I times by 12 then add onto 78. Whatever the answer to that is should equal the amount of months Tony has lived for as this is the grandpa’s age. I firstly tried 12. I times that by 12 which equals 144 but the grandpa is not 144 because Tony’s and his grandpa’s combined ages are 78. Next I tried 5. So I did 5×12 which equals 60 so if this was the right answer the grandpa would be 60 and Tony would be 5 so I would add that together which is 65 but there combined ages are 78 but I was close. I tried 6. 6×12=72 so grandpa would be 72 and Tony would be 6 so 72+6 is 78 which is the combined total of their which that was it so that is the correct answer!

**Summary:** This question I found hard because it took me a lot of guess’s to work out. I finally got there and Tony’s that he will be turning tomorrow is 6.
