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
