Lattice method and Japanese method

LI: To develop the Japanese and Chinese method for multiplication outside the basic facts.

This week for maths we had to make a DLO explaining the maths method we have learned. Using these methods makes your time table easy. But you still need to know your time tables for these methods. I'd prefer using the lattice method if your racing someone on there time tables and you can use the Japanese one when your not in a race or a contest. The lattice method and the Japanese method might be hard at first but when you keep practising it your get better at it.
