Stage 7 multiplication strategies

The Octagon group are currently working within Stage 7. 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 multiplying two numbers together. The strategies used are using distributive properties (using standard place value/ using tidy numbers) and proportional adjustment (doubling and halving). Have a look and decide which strategy you would choose.
