RL> Keep practising adding to make units and ones and then subtracting.
RL> Once the children have a grounding in this the concept of borrowing or

RL> I hope you understand what I'm trying to tell you here as it's hard to

RL> Hope this helps. If you have any questions write back or email me at

Thanks, I was starting that this week. I decided to put the borrowing
off and start on place values. I will email you later as I have just
bought a house and have to go to city hall. Thanks.
Regina
