Doubling

We are learning to work out times two facts from doubling.



If 2x3= 6
Then 4x3= 12
And 8x3= 24
If 2x4= 8
Then 4x4= 16
And 8x4= 32
If 25x2= 50
Then 25x4= 100
And 25x8= 200
If 2x40= 80
Then 4x40= 160
And 8x40= 320
If 100x2= 200
Then 100x4= 400
And 100x8= 800
If 2x125= 250
Then 4x125= 500
And 8x125=1000
If500x2=1000
Then 500x4=2000
And 500x8=4000
