Remembering our Multiplication Facts

This week we decided to set ourselves the target of learning two times tables each week that we don't know. 
First we self-assessed. Did we know all of them, nearly all, most, half or none?
We are busy learning ways to work them out.
If we are learning our 2x, 5x or 10x we use a T-chart to stop us from skip-counting. We have races with Mrs Naden who says she is the fastest skip-counter in the whole world! We use the T-chart and beat her every time even though she is skip-counting super fast! It is a fast way and we call it 'Smart Maths'.

If we are learning our 3x, we use our 2x and then add one more lot on. For example 8x3 is the same as adding 8x2 and 8x1 together.
If we are learning our 4x then we just double our 2x. So 7x4 is double 7x2.
If we are learning our 6x then it's 5x plus one more lot. 4x6 would be the same as adding 4x5 and 4x1 together.
7x is simialr but we add 5x and 2 more lots on. 8x7 would be the same as adding 5x7 and 2x7 together.
For 8x we double our 4x tables. 3x8 is the same as doubling 3x4.
For our 9x we use our 10x and take one lot away. 8x9 is the same as (8x10)-(8x1). That's 80-8=72. If we use this then we can even work out 14x9.


We have coloured in the ones we know on our individual charts. You can see these on our individual blogs.
