MATHS

In room12 we are doing maths like 14 + ? =61.To solve these problems you need to jump a tidy number on a number line then jump back a small number. I will show you some problems and the strategies.                                                                                                                                     

 15 + 57 =72.

strategy.


 So I started from 15 then I jump in tens like 15,25,35,45,55,65,75 so that is 60 jumps.then what I did is a minus 3 so that will be 57.
