Subtraction Strategies

On Mondays, Tuesdays and Wednesdays we do problem solving for Maths. This week Ben and I have subtraction. This the problem.

Qn. 

Emma has saved $403 ( which she keeps in her top drawer ) and she decides to give $388 to Paige. How much will she have left over.

This is my first strategy using place value

and this is my second strategy using equal adjustments

I hope you enjoy my maths:)
