Walt: Use two strategies to solve number problems
What I had to solve in my maths class was 584+something equals 845 so I had to solve it and so I did place value so what I did was 200+500=700 then I did 60+80=140 then I did 4+1=5 then I add them altogether equals 845 then I did another strategies then I did tidy numbers and so I did 584+255=839 then I did 839+6=845 . Then I had to solve another problem and it was 27+something equals 74 so I did place value so what I did was 40+20=60 then I did 7+7=14 then I add them altogether then it made 74.
