Hi Sarah;

because 5 x 20 = 100. How do you do long division?

Hi Sarah;

Look at the drawing. How many times does 20 go into 1?

Hi;

That is not right. 20 can not go into 1. 20 is bigger than 1. Do you understand what I am saying?

hi Sarah

If you want to learn how to do division, I suggest you start with what you can do, eg. take aways.

So instead of 100 over 20 how about

"How many 20s can you take from 100 ?"

See picture.

Hi Sarah;

Take a look over here and let me know what you think.

I have the result, but I do not yet know how to get it.
