3 0 0

3 0


If we multiply 6 by ten it will move into the next column effect.

x10

We must put a 0 in the empty units column to hold the place – 6 x 10 = 60


200 effect.

30

Let’s try with some other numbers

Don’t forget to add the zero in the empty column!

23 x 10 = 230


Let’s try these together! effect.

48 x 10 =

93 x 10 =

134 x 10 =

256 x 10 =

889 x 10 =

480

930

8890

Were you right?


If we multiply 6 by a hundred it will move up two columns effect.

We must put a 0 in the empty columns to hold the place – 6 x 100 = 600


Let’s try these together! effect.

8 x 100 =

15 x 100 =

28 x 100=

134 x 100 =

267 x 100 =
