Stage 6 subtraction strategies

The Hexagon group are currently working within Stage 6. The Numeracy project requires students to use a variety of strategies when tackling addition/subtraction/multiplication and division problems. This video is their demonstration of subtracting using 3 digit numbers. The problems are solved using place value knowledge/place value partitioning/compensating with a tidy number and by reversing (adding instead of subtracting). Have a look and decide which strategy you would use.
