Today I am going to be talking to you about another different strategy called the Rainbow method.

Last week Friday Room 9 had a substitute and the substitute teacher was Mr Tafea.
Mr Tafea was a really cool teacher he taught us 4 different difficult strategies called the Lattice method, Lines method, Rainbow method and the Algorithm method but today I am going to show you how to use the Rainbow method.

So here it is...

  The first thing you do is multiply the two  numbers in the front which is 1x1=1. Then you have to leave a blank space.

  Next you have to multiply the numbers at the back of the front numbers. Which will be 3x1=3 then you add the 3 to your answer which will look like this 1_3

  To get the answer in the middle you need to multiply the numbers you didn't multiply before which is (1x1)+(3x1)=4 so now you have to add the 4 into your answer and it should be...

There is your answer
