To give children practice in checking the answers to subtraction questions. Many children don't seem to be aware of this obvious technique, maybe because it's not been taught them explicitly. These sheets, differentiated to three levels, make them check by adding their answer back to the subtrahend to see if they get back to the original minuend (the number they started from).
Suitable for Key Stage 2, but may well be needed in Key Stage 3 if you find children are not familiar with this from primary school.
