Yes, pastures New you've got it right.

I personally wish I'd been taught the grid method at school, it's much easier.

If your child finds it hard to do say 60x30, tell them to ignore the 2 zeros, so do 6x3=18, then add the 2 zeros back on to the end to give 1800.

this new method of doing long multiplication in a grid is easy once you get the hang of which multiplies with which and is a way to make sure that all the tens and units are multiplied with the right tens and units. when we learnt the multiplication by putting zeros and adding down there was no emphasis on place value. the grid method emphasises a numbers place values and also tries to ensure less mistakes as the teacher can see if the child has managed to multiply the correct digits together my dd1 8yrs is starting this in juniors now and we had a parent maths evening explaining the new methods which parents should be updated with.

wow that is clever! i'm a maths graduate and never thought of breaking down long multiplication in that way. makes a lot of sense to me, more than the way I was taught (as per dieselhead's post).
I imagine being taught this way will help them in the future when they come to multiply out algebraic expressions etc.

I'd never heard of this until my son came home from school using this method, I googled it and found some good sites to explain it to an oldie (46), maths isn't my strong subject and I found it much easier to use.

Primary schoolteacher here, and you're all doing very well!
The grid method is a great way to do long multiplication, although I still use the formal 'old' method for TU x U.
The only thing I don't like about grid is the amount of things you have to add together if you're going into HTU X HTU.
I still use the old method if I ever have to work anything out though!

If you want a fact sheet showing the different methods try https://www.bbc.co.uk/skillswise in the whole numbers section.
I use it all the time when teaching maths to adults who have been taught different ways!
